Pros:Portland pen air staff were great. Pretzels and cookies and FULL bottles of water were appreciated.
Cons:Old prop plane - very noisy and turbulent. At the departure city, I had a flat package ~1/4 inch thick that easily fit flatly into the bottom of the overhead storage bin but did not fit in my carry on. The staff had me physically tie it to my backpack with string to avoid paying a $25 checked bag fee for my carry on (which would then allow me to take the flat package as my carry on). Seemed ridiculous for a flight that was only half full and for which they asked passengers to leave roller bags planeside prior to boarding anyways.
