Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.
