Hey everyone. I have an MR coming up at the end of the month flying all in the same day on 2 oneway tickets: PHL-IAH 0532-0810 IAH-PDX 0850-1118 PDX-IAH 1210-1809 IAH-PHL 1920-2334 And I have the following questions: 1. Can I check in for all the flights in PHL and/or online? Is it okay to check in for my return even if I'm not physically at my destination yet? 2. In the case of IRROPS, would CO/UA reaccomodate me on the return even if it's on a different PNR? I know they don't technically have to, but have others been so lucky?
