I haven't flown Southwest ever since they started charging for bags and having to select your seat.

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.
That's good to know!

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.
They really let you do that? Then just upgrade to premium and get a full refund.

I know this is an impossible comparison since airline prices are always moving and "base fare" is meaningless but I booked seats on a basically empty planes last week for $340. With this deal, they're $290 and the seat map hasn't changed.

Still cheaper but definitely not 40%.

This isn't necessarily true. If you just change the ticket without cancelling it, and keep the same record locator, you will still get the promo.

The person I talked to when I called Southwest with the promo said do not make any changes including changing without canceling it. They told me it will mess it up. Not worth the risk of loosing the companion over a little amount.
