I've flown SW between Vegas and San Diego on two occasions (and AirTran years earlier), but my then girlfriend made the reservations. Therefore, making my own arrangement this afternoon for next month's Vegas trip was a new experience. I feel somewhat disloyal switching from Delta, but the low fares and being able to make changes without the $150 penalty more than compensates. I'm not sure if EarlyBird checkin is all that necessary, but I went for it this time. Even so, the fare is about half what I've been paying on Delta when not using FF miles. I also used Uber for the first time last week going from Suncoast to Gold Coast and again a couple days later from Gold Coast to MSS. (I certainly got my "money's worth" for $0 using my introductory credit on my first trip.) Where I normally would have taken 2 or 3 busses for $1.50 and had the "fun" of walking between stops with my rather heavy backpack, going door-to-door for was well worth the difference. (I don't care about the time savings so much over a weeklong trip, but it was still a plus.) It was a bit confusing at first, but after seeing how simple, fast, and relatively inexpensive it is, I'm hooked. Getting from A to B has never been easier! Guess I'll have to try Lyft next.
