Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Good flight. We were all boarded in good time for departure time but baggage loading had barely begun. So left late. No food just snacks and basic drinks for free (food also for purchase). No entertainment as again, unable to connect with wifi on WestJet despite being a rewards member.

I like the idea of a non-overnight flight to Europe.

The food was very good. I was nit expecting a meal on a red eye trip. I was pleasantly surprised! Plus we arrived a few minutes earlier than expected!

There was no food but a singular cookie for a flight that was over 5hours??? Yeah not fun I was starving and again super cramped plane and you guys need to get planes with screens too, WiFi is nice but common we need more

The plug in to charge our phones are all loose my block would not stay in!!

While I appreciated the food (it was unexpected), it was interruptive for sleeping. We paid extra for reserved seats, but when we checked in they gave us different seats. I had to call WestJet arounf 11:30pm the night before our flight to get this fixed. We were give seats in the emengency row to resolve the issue.

This flight was better than the first. Two of the flight attendants were wonderful at supporting m through nausea and vomiting through the flight. No tv, no food, very interesting. I’ve never paid for wifi (just the $3 chatting) until these 2 flights. This experience has changed my opinion on layovers. Idk if I’ll ever do one again

Entertainment was the only issue. I did not have app & not equipped to watch movie on my phone. Used to other carriers with access to a screen for viewing. Other than that, everything was fine.

Long flight - free food options not reasonable. Drinks fine. Good flight crew.
