We love Midwest
They used to be unbelievable - every seat like 1st class with steak dinners the norm. But, like every airline, they have scaled back after 9/11, esp the meals which are purchase only, no more steak - $5 or $10 for salads, "wraps", etc. There normally aren't enough for every passenger to have a choice from the (limited) menu.
You will get complimentary snack & beverage service and depending on time of day, you still get the hot cookies. In our experience, they've maintained their reputation for excellent service.
They have 2 types of flights now -
saver service (usually to tourist dest) - 3x2 seating, cloth seats, but still more leg room than "normal" flights & yes, fresh baked choc chip cookies
signature service - 2x2 seating, nice wide leather seats with great leg room (& cookies)
