My first experience with PenAir wasn't horrible, but it was far from perfect. It can be summed up by saying this - PenAir needs to get it's act together in Boston, and service their planes.
A little background: PenAir bought out Colgan Air's routes in Maine and now serves as the only regular air service to Presque Isle and Bar Harbor. They have cut back on the number of flights per day, but still provides at least two flights per day. I've heard complaints regarding their service, but had no experience until this week.
The Presque Isle airport went smoothly as usual. Things started to go down hill in Boston as they are unable to check you I'm to your connections. This requires you to head all the way over to the departing terminal and check in. I should qualify this by saying I was flying United so your mileage may vary with other airlines. I remember having to go through this process when Colgan/US Air had this flight. This might be a general comment on all airlines, but one would think you could get your boarding passes all at once regardless of airline.
Our flight crew and steward were excellent, well mannered and helpful. The plane itself looked physically and mechanically sound despite the state of the plane's interior.
My suggestions to PenAir are this: Get your planes cabin serviced. No one likes to be lectured about putting your seat and tray tables in the upright and locked position when it's not mechanically possible. Not to mention it makes you look bad. As it stands right now, I may have you use your service to Boston but I wouldn't recommend anyone get aboard your planes when they have other options.
