Avoid which experience exactly?
If you book a flight is to FLY from A to B (or to C via B, whatever). It's all the same experience. You go to the airport, board, fly, and land, and that experience you get with any airline. Unless of course, you don't mind spending extra 40€, 50€ or 100€ for a dry sandwich and a cup of coffee. Not worthy in my opinion. With that money I go to a good restaurant when I arrive.
