Click the desired seat on the plane diagram presented as part of the WestJet online booking process. The diagram appears after selecting flights and entering contact information.
The plane seating diagram shows the entire plane layout with a color coding system to identify the available seats. The color coding system also shows the cost of each seat, as selecting seats ahead of time costs extra, as of 2015. Exit row seats cost more to choose than other seats. When you find the seat you want, click the picture of the seat, which will turn green to indicate the selection. WestJet passengers also have the option of choosing a seat without a fee during the online check-in process beginning 24 hours before flight departure.
