Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

Lots of overhead storage, good crew, good service, smooth landing.

Lots of overhead storage and a good crew and service.

The small prop plane was crowded and the overhead luggage storage is a smaller than on the jets. Other than that, the crew was good, the flight was on time and the landing was smooth.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

On time. Friendly and efficient staff at check in and flight crew.

Terrible decision to take a night flight. Not enough time to sleep and premium seat has no foot rest ao couldn’t get comfortable!

Late departure, so I missed connection in Detroit. But Delta gave me a great hotel & breakfast. Just sorry I could not get anything from my checked baggage.

Crew was friendly. Lost our luggage and told us it’d be in later in the evening of the day we returned. It was not. Still after 5 days have not received it.

Was on a Swoop plane. No wifi and no Westjet connect
