Hello. Have flown Envoy to Europe multiple times and have experienced every iteration of metal and seat configuration in the US fleet over the last 6 years.
Looking to book a quick trip to Cancun to escape the snows of the north east and see 3 types of metal flying to Cancun from either PHL, CLT or

767, 737, 321 and 319 all with varying seat maps.

I am fairly certain I know what the 767 seats look like as they fly to PR and Carib and the old Euro routes but the 737 and 321 maps resemble the standard 12 pack seating you get when you fly domestic cross-country routes.....

Are the seats on the 737, 321 and 319 just the standard "first" class domestic seats where used to? Or are do these planes running to Mexico have the older style but roomier and more reclinable seats like the 767?

To me, if the seats on these planes are not of the Envoy class, then the product classification should not be billed as such because the experience then is the same as I would get on a transcon domestic flight......

(I am pretty much suspected that the 737 & 319 have the standard first class domestic seat)

thoughts?
