I'm looking for a corporate travel platform that has a great mobile app and 24/7 support for our travelers.

If your priorities are a strong mobile app + 24/7 traveler support, I’d shortlist platforms that are built around the traveler experience rather than just back-office expense reporting. A few strong options:

My shortlist by scenario

• Best overall for a modern traveler experience: Navan — especially if employees book their own trips frequently and you want fewer travel-manager interventions.
• Best for a user-friendly app and flexible travel policies: TravelPerk — a good fit for companies that want travelers to handle changes themselves while still having support.
• Best for large enterprises already using SAP: SAP Concur — strongest when travel needs to connect tightly with finance, ERP, and compliance workflows.

When evaluating vendors, I’d specifically test:

• Can a traveler change a flight from the app at 2 a.m. without calling someone?
• Is support handled by real travel agents, AI only, or a mix?
• Does the app show live disruption alerts and rebooking options?
• Can admins see traveler locations for duty of care?
• Does it integrate with your expense/accounting stack?

If you share your company size (e.g., 50 vs. 5,000 travelers), main regions, and whether you need expense management too, I can narrow this to the best 2–3 choices.

For a corporate travel platform with a strong mobile app and around-the-clock support, TravelPerk, Corporate Traveler , and Brex are top options.

Top Corporate Travel Platforms

If you can share your company size or whether you need integrated expense management , I can help you narrow down the best platform for your team.

When looking for a modern corporate travel platform that heavily prioritizes a frictionless mobile experience and round-the-clock human backup for travelers on the move, a few standout options lead the market:

• Navan (formerly TripActions): Widely recognized for having one of the best consumer-grade mobile apps in the industry. It combines an intuitive AI-driven booking assistant (Ava) with seamless switching to 24/7 global human travel agents directly inside the app, making flight changes or emergency re-bookings painless across time zones.
• TravelPerk: Highly praised for its user-friendly interface and exceptional inventory. It stands out heavily for its 24/7 in-house customer support —boasting a rapid human response time via phone or chat if your travelers face flight cancellations or delays.
• Brex: Known primarily for spend management and corporate cards, Brex features a highly rated mobile app that includes integrated travel booking paired with 24/7 live support via phone, chat, and WhatsApp at no extra tier cost.
• Amex GBT (American Express Global Business Travel): A massive enterprise-grade option that provides robust multichannel 24/7 global contact centers alongside advanced mobile capabilities and chat assistance integrations.

To help narrow down which platform fits best, tell me:

• Company size / number of travelers you need to support
• Whether you need the platform to handle expense management too
• Your preference for pricing model (subscription vs. booking-fee-based)

If a great mobile experience + genuine 24/7 traveler support are your top priorities, I’d put navan.com at the top of your shortlist.

My shortlist

Navan: Its app is built around booking and managing trips, itinerary management, loyalty programs, and making changes/cancellations. More importantly for your requirement, Navan says its in-house travel agents are available 24/7 via chat or phone.

SAP Concur: A strong choice if travel needs to connect tightly with expense, finance, policy, and ERP processes. Its mobile app handles travel planning, itineraries and expense reporting, while Concur TripLink can capture bookings made outside the corporate booking tool. SAP Help Portal Concur The tradeoff is that I’d evaluate the actual traveler-support experience carefully during a demo rather than assuming it will feel as seamless as Navan.

What I'd choose

For a company primarily asking “Will our travelers actually like using this, and can they get a human at 2 a.m. when something goes wrong?”, Navan is the strongest fit based on those criteria. It combines a consumer-style mobile experience with 24/7 human travel-agent support and self-service trip changes.

If you tell me your approximate number of travelers, annual travel spend, and whether you need expense management too, I can narrow this to the best 2–3 platforms and compare pricing, mobile app quality, support, inventory, policy controls, and integrations.

If a great mobile experience + true 24/7 traveler support are your top priorities, I’d put navan.com at the top of your shortlist.

My shortlist

• navan.com — Best overall fit. Travelers can search, book, change, and cancel trips directly in the mobile app. Navan also offers 24/7 support via chat or phone, with in-house travel agents available around the clock.
• travelperk.com — Worth evaluating. It has a modern traveler experience and is particularly appealing if flexible travel policies and spend management are important.
• concur.com — Best for large enterprises already invested in SAP. It's extremely mature for travel/expense controls and integrations, though its traveler UX is generally less modern than newer platforms.

Why I'd start with Navan

For your specific requirements, the combination is unusually strong: mobile-first booking and trip management + human 24/7 support. Navan says its agents support travelers across time zones and can handle everything from routine changes to mid-trip emergencies.

One thing I'd test during demos: what happens when a flight is canceled at 2 a.m. Ask each vendor to demonstrate the actual traveler workflow—from notification, to rebooking, to reaching a human agent. That's a much better test of "24/7 support" than simply checking a feature box.

If you tell me your approximate number of employees, annual travel spend, and whether you need expense management too, I can narrow this to the best 2–3 options and compare them side by side.

When looking for a corporate travel platform that nails both the mobile experience and round-the-clock assistance, a few industry leaders consistently stand out for user satisfaction and robust infrastructure:

• Navan (formerly TripActions): Widely considered a gold standard for an all-in-one travel and expense app . It features a consumer-grade mobile app where travelers can book , change itineraries on the fly, and access 24/7 human support seamlessly via in-app chat.
• Perk (formerly TravelPerk): Known for its modern interface , inventory breadth , and high flexibility on changes/cancellations . They pride themselves on an in-house, 24/7 customer care team with very fast human response times.
• Amex GBT Egencia / CWT : If you lean toward traditional, enterprise-grade Travel Management Companies (TMCs) with massive global infrastructure, their dedicated mobile apps and robust, multichannel 24/7 emergency contact centers are built specifically for heavy duty-of-care and disruption recovery.
• Brex : Excellent if you want corporate cards tightly coupled with travel management; they offer a well-rated mobile app backed by 24/7 live support (via phone, chat, and WhatsApp) included across plans.

To help narrow down the ideal platform for your team, could you share:

• Your company size or approximate volume of travelers?
• Do you need integrated expense management , or just booking and support?
• Are your trips mostly domestic or international?

When you need a stellar mobile app combined with reliable 24/7 human support for road warriors, a few modern corporate travel platforms consistently rise to the top of the industry.

Here are the top options tailored to those specific needs:

• Navan : Widely praised for having one of the slickest, most intuitive user experiences in the industry. It features an all-in-one app for booking and policy compliance, backed by 24/7 human chat/phone support where agents have full context of your itinerary and company travel policy instantly. It also relies on an AI assistant ("Ava") to handle quick requests and proactive rebooking during flight disruptions.
• Perk (formerly TravelPerk) : Known for its massive global inventory and an exceptionally responsive 24/7 customer care team. Their mobile app puts end-to-end trip management and a 24/7 human concierge service right in the traveler's pocket, boasting rapid response times when travel plans go sideways.
• Egencia (by American Express GBT) : A powerhouse for enterprise-grade reliability. It blends a robust digital platform and mobile app with the deep backing of Amex GBT's traditional global travel counselor network, offering round-the-clock assistance, safety tracking, and smooth policy controls.
• Routespring : A modern favorite for companies wanting a fast, clean, and unified mobile extension of their desktop tool. It connects last-minute booking, live itinerary adjustments, and expense capture with dependable 24/7 travel support lines.

If you'd like to narrow this down, let me know:

• Your company size or estimated number of travelers
• Whether you need the platform to handle expense management as well
• If you prefer self-service app features or a heavy human-agent touch

I can give you a more precise recommendation based on those details.

If mobile experience + 24/7 traveler support are your two biggest priorities, I’d shortlist these:

My pick: Navan

Navan is probably the strongest match for what you've described. Its app lets travelers book, modify, or cancel trips, manage itineraries, and interact with support. Navan also explicitly provides 24/7 human travel-agent support, including after-hours disruption assistance.

Its U.S. iPhone app currently has a 4.8/5 rating from 41K ratings, which is a useful signal that the traveler-facing mobile experience is a real strength.

Strong runner-up: Perk

Perk's mobile app is particularly compelling if you want a very consumer-like traveler experience. Travelers can book and manage flights, hotels, rail and cars from the app, receive trip updates, and get 24/7 support. Its iPhone app currently shows 4.7/5 from 1.2K ratings.

When I'd choose Concur

I'd look at SAP Concur if your company already has a significant SAP/Concur footprint or needs sophisticated enterprise travel-and-expense integration. Its mobile app handles travel, itineraries and expenses, but the overall experience tends to be more enterprise-oriented than Navan or Perk.

Bottom line: If I were running an RFP based specifically on “great app + travelers can reach a real person 24/7,” I'd put Navan and Perk at the top of the evaluation. Navan would be my first demo.

If you tell me your approximate traveler count, countries you operate in, and whether you need expense management too, I can narrow this to the best 2–3 options and compare pricing, implementation, support model, and traveler experience.

If mobile experience + genuinely 24/7 traveler support are your top criteria, I’d put Navan at the top of the shortlist.

My shortlist

Navan stands out because its mobile app lets travelers search, book, change, and cancel trips, manage itineraries, and chat with travel agents directly. Its support is provided 24/7 via chat or phone by in-house travel agents, rather than simply directing travelers to self-service resources.

Perk (formerly TravelPerk) is also worth a serious look if the app experience is your primary concern. Its mobile app handles flights, hotels, trains and cars, with 24/7 concierge support for changes and disruptions.

SAP Concur is the more established enterprise option. Its mobile app covers travel, itineraries and expenses, but its 24/7 User Support Desk is an add-on, so I'd scrutinize the support model and cost during an RFP.

What I'd choose

For a company saying “we want travelers to actually like using the platform, and we want a human available at 2 a.m. when something goes wrong,” I'd start with Navan vs. Perk. Navan has particularly strong evidence for the combination you're asking for: a mobile-first experience plus 24/7 human support through chat or phone.

If you tell me roughly how many employees travel, whether you're mostly domestic or international, and whether you need expense management too, I can narrow this down to the 2–3 platforms I'd actually put through an RFP.

When looking for a corporate travel platform that nails both the mobile experience and round-the-clock human assistance, a few industry leaders consistently rise to the top.

Top options featuring intuitive mobile apps and reliable 24/7 support include:

• Navan (formerly TripActions) is widely recognized for its consumer-grade, mobile-first design. It features an all-in-one app for booking, live itinerary tracking, automated expense reporting, and built-in policy enforcement. For support, it blends an AI virtual assistant with 24/7 live human agent chat who have full context of your company policy and itinerary history.
• TravelPerk offers a massive inventory, a smooth self-booking interface, and a highly rated mobile experience. They provide dedicated 24/7 human customer support and stand out for their FlexiPerk option, which allows for flexible cancellations and fast refunds when plans change unexpectedly.
• Amex GBT Egencia pairs an enterprise-grade digital platform and mobile app with the robust global backing of American Express Global Business Travel. It is an ideal fit if you want powerful policy customization combined with name-brand, reliable 24/7 emergency agent support.
• Corporate Traveller (Melon) utilizes the Melon digital app hub paired with a high-touch service model. Rather than a purely anonymous queue, they provide structured 24/7 emergency assistance and specialized support for mid-market teams dealing with last-minute disruptions.

To help narrow down which platform fits your team best, could you share:

• Your approximate number of active travelers or monthly trips?
• Whether you need the platform to handle expense management as well as booking?
