Most travel apps are bloated or redundant. These 12 are worth the space on your phone — one best-in-class pick per category, with the second-best option noted where it matters.
The most accurate real-time flight tracker for US domestic flights. Shows the plane's current position, speed, altitude, and actual gate updates. Push notifications for delays, gate changes, and arrival times.
Best for: tracking your own flight or someone picking you up. Most data-rich option for US flights.
Best for international tracking and the most visually engaging interface — you can watch planes move on a live map in real time. Better coverage of international routes than FlightAware.
Best for: international travel, enthusiasts who want to see the whole sky, tracking a specific tail number.
When to use which
Domestic US flight → FlightAware. International → FlightRadar24. Both are free. Both are worth having.
Automatically parses email confirmations — forward to plans@tripit.com or grant Gmail/Outlook access — and builds a master trip itinerary. Handles flights, hotels, car rentals, and restaurant reservations.
TripIt Pro ($49/year): adds real-time flight alerts, seat tracking, and alternative flight suggestions — genuinely useful for frequent travelers.
Best for: anyone who has more than 2 bookings per trip and does not want to dig through email at the airport.
The most powerful flight search tool, especially the date grid and price tracking features. See the cheapest dates at a glance, track specific routes, and set fare alerts.
Best first stop before any flight booking. See How to find cheap flights for the full search strategy.
Predicts whether flight prices will rise or fall and recommends when to buy. Best for travelers who have time to wait and want a data-driven signal on timing. Less useful when you need to book immediately.
Hopper also sells price freeze options — for a fee, you can lock in a price for a few days. Worth it occasionally on volatile routes.
The single most important app to have. Download your airline's app before every trip — it sends real-time gate change alerts, allows same-day change/standby, and shows your upgrade position. This is not optional for a smooth trip.
Must-have: Delta, United, American, Southwest, Alaska, or JetBlue app — whichever you are flying.
Airport maps with gate locations, estimated walking times, and store/restaurant finder. Useful for unfamiliar airports with complex layouts (ORD, DFW, ATL, LAX).
Alternative: most airline apps now include in-terminal navigation at their major hubs.
Download the languages of your destination for offline use — the camera translation feature (point at a menu or sign) works offline and is genuinely impressive.
Tip: download offline language packs before you leave home — airport and hotel WiFi is inconsistent.
Near-universal messaging outside the US — Europe, Latin America, Asia. If you are meeting foreign contacts or family, make sure you have WhatsApp installed before you leave.
The best app for spending money internationally. Real exchange rate (no markup), low conversion fees, and works as a debit card or for international transfers. Order the physical Wise card before your trip.
Similar to Wise — real exchange rates, free ATM withdrawals up to a limit. Revolut's paid plans include travel insurance. Useful if you want currency budgeting features alongside your spending card.
Generates a packing list based on your destination, trip length, and planned activities. Surprisingly useful for reducing decision fatigue before a trip.
Alternative: for most people, a stored notes list (Apple Notes, Notion) that you refine trip-by-trip works just as well.
FlightAware for domestic US flights (most accurate); FlightRadar24 for international and a broader live map view. Both are free and worth having.
TripIt free is excellent. TripIt Pro ($49/year) is worth it for frequent travelers who want real-time alerts and alternative flight suggestions — skip it for occasional travelers.
Use Hopper for its price prediction feature, but book directly with the airline or via Google Flights for the actual purchase. Booking through Hopper adds a middleman that complicates changes.
Download your airline's own app — it is the most useful single app for gate changes, boarding passes, and same-day flight management. Add FlightAware and your airline app and you have 80% of what you need.
Know when to leave — not just which apps to pack
