Input request: I am going to be flying from Paris to Omaha on an AA 767-300. I have enough AA miles for the 2 coach seats. I'm 6 ft. tall so not some freako giant but is it even possible for me to spend 9 to 11 hours in that coach seat? I can transfer 40k SPG points into AA to get the adnl. 50k AA miles needed for 2 business class seats. Really don't want to use all those SPG though. Also, my flight options are through ORD with a 6 1/2 hour layover or through DFW with a 2 1/2 hour layover. The flight from Paris to Dallas is 2 hours longer though which would be 11 hours in that seat. Total travel time is 2 hours more total via Chicago. So, use the SPG to upgrade the seats? Fly coach into ORD or DFW? Really wish I would have gotten one more AA card at some point so this wouldn't be an issue.
