CALGARY — WestJet is introducing a fourth fare bundle, Plus Lowest, and updating its fee structure to offer lower fees to clients who make changes to their booking more than 60 days from their departure date. The changes take effect May 11.

WestJet now offers two fare options under the Plus umbrella: Plus Lowest and Plus Flexible.

“When you book Plus Lowest for their clients they will enjoy the same Plus onboard experience,” said the airline. What’s new? They will pay a lower fare, change fees will apply and the fare will be non-refundable.

Plus Flexible clients will also get the same Plus onboard experience, with no change fees and the fare will have a refundable option.

WestJet said there will be no change to commission as a result of this change. “Travel agents will continue to earn 8% commission for both Plus Lowest and Plus Flexible.”

The Plus Lowest fare bundle will include H and W fare classes, and the Plus Flexible fare bundle will include K fare classes. Econo includes C, I, D, X, G, P, M, L and Q. Flex includes B, V and Y. Plus Lowest includes H and W and Plus Flexible includes K.

Both Plus Lowest and Plus Flexible passengers get the onboard amenities included in the current Plus fares, such as extra leg and elbow room (an empty middle seat on 737 aircraft and wider seats on 767 aircraft), two checked bags, advance boarding, priority security screening (at select airports), premium food and beverages (including beer, wine and spirits) and lounge access in London (Gatwick), LGW.

WestJet is also offering lower fees for changes made to bookings that depart outside of 60 days. These new fees are effective for bookings made on or after May 11.

Change fees will still be based on region. The regions include: domestic; transborder/international sun; and Europe. Fees will still be charged per person, per transaction for all regions.

To compensate for the short notice WestJet said it is providing a 30-day grace period. “Until June 11, 2017, if the incorrect fee is charged for the 24 hour change/cancel rule, please contact our Travel Support Team (TST) at 1-877-664-3205 and one of our TST agents will be pleased to assist you with correcting the file without penalty.”
