TerminalTrail
A real-time LaGuardia (and broader NYC airport) concierge app that warns you when your airline has been reassigned a new terminal or gate, then walks you through the fastest route, food, and rebook options.
Frequent NYC flyers — business travellers and tourists — whose airlines (JetBlue, Spirit, Delta, American) keep moving between terminals at LGA
- Push alert the moment your booked flight's terminal or gate changes, with a 'leave now' countdown based on your location in the airport
- Terminal-by-terminal food, lounge, and accessibility map refreshed monthly as concessions rotate
- Multi-airline rebook suggestions when your flight is delayed or cancelled, prioritising slots airlines just acquired
- Offline mode that pre-loads your itinerary, walking maps, and gate history before you reach the airport
JetBlue's win of Spirit's LaGuardia slots and the ongoing Marine Air Terminal reshuffle mean terminals are shifting mid-summer — a moment of peak traveller confusion.
Demand is narrow: only NYC-LaGuardia flyers care about this specific terminal-reshuffle window, and the cited Trend note is from GB (not US) suggesting searcher base may be small; dedicated LGA live tracker (Horsebox) exists already.New York LaGuardia LGA - Apps on Google Play ↗JetBlue wins Spirit slots at LaGuardia, considers moving terminals - CNBC ↗
Crowded: Flighty, FlightAware, FlightElite, and the official LaGuardia app all push gate/terminal change alerts; Horsebox has a dedicated LGA live tracker that already covers gate, terminal, and delay alerts.Best App for Real-Time Gate Change and Delay Alerts in 2026 ↗Mobile Flight Tracker Apps - FlightAware ↗Flighty — Live Flight Tracker ↗
Proven willingness to pay for flight alerts (Flighty Pro $47.99-$50/yr, lifetime $250-$299), but TAM is limited to a single NYC airport's frequent flyers — most travellers won't subscribe vs. free airline-app alerts.Flighty Pricing (2026) ↗Flighty Review: The Flight Companion Worth The Price? ↗Is Flighty Pro Worth It?

Time-bounded: JetBlue-into-Marine-Air-Terminal move is real and happening now, but once terminals re-stabilize the core 'warn me' value drops; airports and airlines are also folding this into their own apps, eroding standalone utility.JetBlue Wins Spirit's LaGuardia Landing Slots, Will Move Operations To The Marine Air Terminal ↗JetBlue wins Spirit's LaGuardia slots after saying it can't make money - View From The Wing ↗
Standard mobile app plus third-party flight-data feed (FlightAware/OAG APIs carry real cost), a routing layer within one airport, and rebook integration — achievable solo in months, but data licensing and airport-map maintenance are non-trivial ongoing costs.Home - LaGuardia Gateway Partners ↗6 Best Real-Time Gate Information Apps For Connecting Flights ↗
