Airline comparisons become more useful when I look beyond the original fare and track what happens once the trip starts. Delays, baggage handling, rebooking, seat comfort, app updates, and staff communication can affect the same itinerary in very different ways. I also compare how quickly information appears when the schedule changes and whether self-service options actually work. In that comparison I add worst domestic airlines around my notes on reliability and disruption handling rather than focusing only on onboard comfort. Those operational details often tell me more than a small price difference at booking.
