Never liked these smaller jets, no room, you almost sit on the person next to you. Never fails that the person in the seat in front of you decides to recline the seat so the back of the seat is in your face. Wifi access was terrible, connects for a few mins they drops. Wish there was a way to restrict selecting flights with the smaller jets.
