Let me give you the game. None of these airlines likely to crash. You mostly worried about customer service and comfortability.
Spirit not really a bad airline as far as flying. All of these airlines no frills these days. It’s the customer service that make them woat. I done flew Spirit plenty of times and I be ready to slap fire from them nikkas anytime I gotta deal with them at the ticket counter or over the phone. But in general they gon get you there for cheap. But they some hoes, for real.
Frontier, they about the same prices as spirit. I only flew them a few times but I assume they got horrible customer service too.
As far as extra fees and shyt, I refuse to travel with nothing more than a carry on so I don’t never have no issues with no bags on any airline. So I can’t speak on that. I fly a lot and I’m either bringing a duffel bag or bookbag. I don’t do luggage.
American, United, Southwest, etc… All them shyts are a step up customer service wise but they not that much better than Spirt and frontier to be honest.
Delta is the only airline where it’s a big leap in experience. Delta gon tax you though. But they the best airline. Great customer service and more comfortable than the other airlines.
Now to the seating tips. If you tall, pay for an aisle seat or emergency row seat if you can. shyt only gonna be like $10-$15 for the seat.
If you tall and going on a flight longer than 3 hours, you must get that emergency row seat for your legs.
If you tall and on a flight for 4 hours or more, you might wanna bite that bullet and pay for first class if you can’t get that emergency seat.
Delta got the best first class. They gonna knock your mothafukking head off. It’s worth it if you 6’5 like me and on one of them long flights.
