Verified travelerFlew with Air Canada-Sept 2026
The seating on the left side of the plane had just 2 in the row which was nice but the seats we chose had very little room. Paying for extra leg room would have been a plus.
HibaFlew with Porter Airlines-Aug 2024
People with kids or disabilities should be informed that boarding this flight requires taking stairs and a bus. Also, although this was over 5 hr flight, we were only served tiny snack bag and a drink. WiFi was great👍.
