Just a reminder: If you registered for the recent companion pass promotion and bought tickets last week… Do not change those tickets, even though the price might have gone down. You will no longer qualify for the companion pass promotion.

Interesting. Every Southwest flight I booked in the last couple of weeks is actually more expensive this week after this '40% off' nonsense.

I don't know if it's just me. I flew with Southwest 6 times recently. Each time it was delayed at least 40 minutes. Frown They were not bad before. Now I hesitate to fly with them.

Cancel and buy with refund, the remaining refund will expire in 6 months, use it before expiration

I believe that before canceling… You can pay to upgrade from basic to choice… and then cancel… And the credit will be good for a year.

Same here. Cancelled flight on the way and an hour delay on the return.
