Where does Allegiant Air fly? The G4 route map

The busiest G4 markets include Catasauqua to Midway, Sunnyside to Las Vegas, and Fletcher to Fort Lauderdale.

Data current as of July 31, 2026, refreshed on an ongoing basis as new schedules and seats are confirmed.
What 2LNR tracks on Allegiant Air
2LNR tracks confirmed upgrade inventory on American, Delta, and Alaska, and award availability across roughly 30 airlines, segment by segment and date by date. Open any G4 route below for a calendar of what is actually open, or watch a route and get alerted when space appears.
Availability by date
Each route opens a calendar of departures with confirmed upgrade and award space, so you can see which dates already have room instead of checking one flight at a time.
Alerts when space opens
Premium seats turn over fast. Watch a G4 route and 2LNR notifies you by email, SMS, in-app, and push the moment space appears.
