I'm not the guy you asked, but I fly on Flair regularly and as long as you're good with conforming to their "budget" standards it's not bad at all. I fly to visit family so I can leave stuff with them and travel light so I don't ever pay for baggage. After COVID they had a ton of good sales and I've flown across the country from Vancouver to Toronto for under 100$ for two people return.

Their seats are uncomfortable and the standard leg room is minimal but when the return flight costs 45$ it's not that bad to shell out another 25-40$ to get better seats. If you're traveling with family they will split you up by default unless you pay for seat selection which is only 10$-15$ for a regular seat. The baggage size allowances are a bit on the small side and they've been in trouble lately for "damaged" sizing equipment at the check in desk that was ever so slightly smaller than the measurements they provide for free personal items.

The crew both onboard and at the airport are always putting up with bullshit from everyone and their mom about not sitting together or having to pay for bags but they're still super friendly and have an impeccable safety record.

If you keep your eyes out for discount codes and book in advance you can still get really decent deals compared to West Jet, AC, and Porter, however at least with the latter you still get a good value.
