Had same thing happen for July 18 trip. Had our preferred times, non-stops to/from Vegas. Then that dreaded email from SWA "Here are your flight changes." Oh, no.
Plane changes in Dallas and again in Phoenix. What?
Nice lady at SWA re-booked it back to the original. All just fine. Then that dreaded email again.
Turned out SWA had wiped the non-stops (and other flights) off those dates.
So I re-booked same good flights for July 27th, non-stop, great times. Uh, oh, that dreaded email again, all non-stops wiped off the schedule. Fiinally got it down to 1 plane change (Dallas Love) each way. We are spoiled by going non-stop for so long.
Can't tell when they resume because even though you see what you see on the web site, they were/are modifying flights as things were happening (and people probably cancelling flights like crazy). I'm guessing the reservations people on the phone weren't getting the changes right away.
Hope your flights stay good, Bobby. That far out they probably will.
I have November flights booked for SEMA, non-stops, but who knows? I won't be surprised if they change us again.
