Thanks so much for your info!! I have the option to choose a later flight from ARN to UME 520pm vs 320pm, just choosing SAS instead of Norwegian for the connecting flight... It's an extra 150 bucks or so total for the 4 of us but it sounds like the better bet just in case things go wrong... It only puts is in Umea about 2 hours later than the 320 flight and the planes have similar comfort levels for the short hour flight so I'm going to air on the side of caution and go with the later flight. Thanks again for all the help!!!
