I just booked a “Premium” seat on a 737-700. The picture on the booking page showed 2x2 layout, and so did the seat map when I selected a seat.

However, my e-mail confirmation says “Premium economy,” so that made me look at WestJet’s website for the seat map of a 737-700, and it shows 3x3 with middle seat blocked.

So what should I expect? I thought I read that all -700s are 2x2. Note I’ve never flown WestJet before.
