I love Southwest so much. I've gotten a few free flights with them with the points I've collected (they have a great rewards program!), and their crew is always great. People that genuinely like their jobs. I have them booked for my next trip, and this morning I got an email that they changed my flight - it went from a direct, 2hour flight in the evening to a 6.5hour itinerary with 2 stops!! Easy-peasy, I can fix this, I just logged into the system under the reservation, click "change flight" and am able change their crazy itinerary it at no charge.....because of their changes (and awesome change policy) I'm now on a new direct flight that gets me into Orlando 5 hours earlier at no extra cost. I'll take it!
They're so easy to deal with, they're not always the cheapest option but when they are I'm a happy camper
