A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

Flight was delayed over 2 hours, then landed at a different airport!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Wish we had music during take off and landing like the last flight

Porter is what Westjet used to be. Staff were great

travelling in 14th of April and now we are in 17th , I have not received my lost/delayed bag... this is very bad and the worst part is their call center is not able to see where is it!!!!

Flight was supposed to be at 3 didn’t fly out until 6:30
