Top 5 airlines serving from Ottawa to the United States
Long delay die to pet mix up. Also bags took forever to get to carousel

Porter, like most airlines, need to improve their baggage policies. In reality, there are no longer 'cheap flights' because passengers pay exorbitant baggage fees.
One United employee a little impatient, also on flight WiFi was out for some time. I was happy to receive a complimentary alcoholic beverage for volunteering to check my carry on bag.
Very rushed and stressful Transfer at Pearson. Baggage delayed, I have been advised is coming, but not sure when.
Boarding was a breeze and the attendants at the airport were very helpful
Not to long of a trip, crew where very good.
Took forever to board. Didn't leave until an hour past scheduled time.
Seats suck. Only one drink service in three hours with the flight attendants being more attendant to their phones than the customer. Painful in the extreme.
I don't like anything. The crew was so bad. Misbehaved badly. The worst flight.
Long wait for baggage check in with only one on site attendant.
The worst airlines I have seen in my life they don’t respect anyone they don’t care about anyone they lost our luggage and no one is responding. We waited for five hours to get our luggage back.🤬🤬🤬👎🏻👎🏻👎🏻👎🏻
Great staff. Cramped seating for someone 5 feet, 2 inches and average weight. So if you're tall or heavy -- good luck. Even if you wait until the 24 hour checkin time, you still charge for seating. Really? So either it is a less-than-pleasant experience or pay the price of a "big name" airline. And if I'm going to pay their prices, why would I fly in your cramped seat? So, in the end, you want to give less comfort for the same prices as Air Canada. Go figure.
The airplane smokes and they think it's normal.... this is sign of deterioration
Flair aircraft smokes before takeoff... and this seem normal to air hostess..... smoking aircraft is not a good sign of safety
Flair’s customer service isn’t helpful at all and their refund is a scam
Everything was great. Got out 5 minutes early and had a nap on the overnight flight.
Wifi was down on this flight but I had a movie downloaded.
Horrific airline. This trip didn't even happen!! We got to the airport and were told at check-in that our tickets were canceled WITHOUT NOTICE! I begged the agents for more info and was told we were blacklisted for using a fraudulent credit card. The card was debit and the funds were already taken out! The desk agents all left, and we were left with zero solution. We had to book another flight with a different airline which cost us $2300 in addition to the $550 Flair already took from us. I have been on the line for 30 minutes to speak to an agent. Does not look promising. AVOID FLAIR AT ALL COSTS.
