The 737-700 of AM has standard Business Class Seats. Non different than Delta or Continental with the only issue being that AMīs are not made of leather. Pitch is the same as in Delta or Continental. I havenīt done MEX - SEA but i have done MEX - JFK on this bird and also on the 737-800 from AM. The 800 has like 5 or 6 rows of Clase Premier (a lot more seats), and the 700 has 3 rows, both on a 2-2 config. They do not have power ports and the service is great with an excelent food menu for Clase Premier. I would definitely recomend you to use your miles on this trip on AM Metal.
