The no seat assignments policy on SW is awesome. You literally just check in on time to get on the earlier groups through a mobile app. Click a button 24 hrs before your flight. Boom you're in group A. B at worst. It's straight first come first served. At worst, you can pay $25 extra for the early bird to be in the A group and not stress about check in. Then then line you up based on your spot, and you just walk on and pick which seat you want. Plus SW doesn't charge you to check a bag.
Egalitarian shit. None of this class based, money grubbing crap. Those types of policies are the reason we have "fast passes" at airports now and then of course then even faster "fast passes".
Other airlines are also charging you after your tickets to choose your seats and they charge more based on the seat. And charging for bags. And everything else.
Assigned seats also ruined the theater experience for the same reasons.
