Why it's similar
United Airlines is a top full-service alternative and the most-reviewed airline app here, with a 4.78 rating across 7,900,000+ reviews. It delivers booking, check-in, mobile boarding passes, bag tracking, and live updates, matching the Alaska app's full toolkit.
How it differs
United's routes, fees, and MileagePlus program are entirely different from Alaska's Mileage Plan, so loyalty and pricing do not transfer. Its larger, busier app and hub network give a different feel from the seed's focused West Coast carrier.
