CO 777 Seat maps
 

I just noticed today a change in seatmaps from the new shape of the lie flat seats they are using to the old orange squares. Y looks a bit different also.

I am booked EWR IAH in August in F, and was so disappointed to see the old seat maps back. Anybody have any idea why?

I did a random check of a couple flights today, and they showed the old seating chart back.

Are they starting to mix UA and CO equipment? I bought a F ticket, and will be furious if I get a UA plane.

No idea what's going on, but the 772s between EWR and IAH are substituted out fairly frequently. No one should pay extra for these flights and expect they'll definitely be on a flat bed. Pretty significant chance you may be on a 737 or 753 with domestic F.
