Airline reviews

Our itinerary included a 1 hour and 30 minute layover, which should have been sufficient under normal circumstances. However, our original flight was delayed. Before we even deplaned, we were instructed to collect our checked bags from baggage claim, clear immigration and customs, and then recheck our bags for the connecting flight. The airline knew—or should have known—that this was impossible. Checked baggage acceptance closes one hour before departure, meaning there was no realistic way for passengers from the delayed flight to recheck their bags in time. Despite this, the airline gave us misleading instructions instead of informing us that we would likely miss our connection. We completed immigration and customs in approximately 10 minutes, but our checked bags did not arrive at the carousel for more than 30 minutes. After collecting them, we had another 10-minute walk to the baggage drop area, only to find that no airline attendant was present. We then went to another airline counter, where an employee told us this had happened before and that there was nothing they could do because the baggage acceptance window had already closed. At that point, there were still 40 minutes remaining before our flight's departure, yet no one was willing to assist or offer a practical solution. When we asked to be rebooked, we were simply told to call the airline's 800 number ourselves. There was no accountability or customer support at the airport, leaving us stranded in a foreign country with no immediate assistance. After finally reaching an agent on the 800 number, we were rebooked on a flight for the following day. However, we were initially told that the airline would not provide any hotel accommodation and that we would have to arrange and pay for it ourselves. Only after making multiple calls and speaking with several different agents did one representative finally issue a hotel voucher. The entire experience was an exhausting and frustrating ordeal. What should have been a 20-hour journey ultimately became more than 30 hours due to the airline's poor planning, misleading instructions, lack of accountability, and inadequate customer service. The unnecessary delays, confusion, and absence of meaningful assistance caused significant physical exhaustion and severe mental stress. This experience fell far below the level of service passengers should reasonably expect.

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

They lost my bag. Hopefully it will be here tomorrow.

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

I like the leg room in the exit isle..easier to get past people and I did t have to pay extra! Westjet changed my return flight time to a night flight 2 weeks before I left and left me hanging with NO HELP to resolve all the frustration they caused since I booked thru BudgetAir. They receive the lowest of star ratings I can give (if there was negative stars I’d be using those) for customer support and an overall bad score for the rest of the experience! So sad cause they used to good :)

Better boarding process, but not the fault of the airline… people are dumb.

It was a swoop flight at a west jetfare… the plane was literally a swoop branded plane.. I pay extra to NOT fly the budget carriers like swoop and flair so needless to say I was annoyed when both my outgoing and return flight were on swoop planes.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

Both flights we boarded and had to wait 1 hr/45 m respectively before leaving the gate. This was over and above normal times. Seats and space not comfortable.
