Doing CLE-IAH-SAN r/t and am watching -
Seat map has been at 8 F seat open for the last couple of weeks.
Not sure if any plats on the flight, but nothing changed on the map at 5 day window.
No change at 3 day for me (or anyone else as far as I can see).
Im being offerred the same buy-up to first for $390 each way (no thanks) that I have since booking.
Will keep posted.
