This makes me glad that I chose the 18 exit row. Is the leg room there as big as on MDs ? What about the underseat storage: is it allowed in exit rows ? Boy, its been awhile since I flew in coach

Leg room on row 18 seems about as much as on MD-80 exit rows. Underseat storage is like on the rest of the plane - it has to fit under the seat in front of you. The underseat storage area is not noticably different from other coach seats.
