Thanks for all the help. I should have given more details for OSL. The QR business class ticket is ATH DOH OSL then 2hrs later AA award ticket on AY - OSL HEL DFW , one of us in business and one in econ (AY only releases one business award ticket to AA). The econ ticket should get the job done since we will be home and can recover from no sleep/food. US passports, so I do think we will have to do passport control in OSL and again in HEL which may take up all our time unless the flight is early. Hopefully the food on the planes will be good enough so missing a lounge will not matter; just like a quiet spot if in the airport for long. Just trying to set expectations if whether it would even be worth trying to get in the OSL Lounge.

Did look at the stops in DOH closer, first stop is for 8 hours and 2nd is for 5. On the 8 hour stop probably, we will probably exercise and shower.

All fun things to consider. Thank You.
