I'll be flying EWR-MXP (wideroe deal!) in 2014, and on the return I'm on the UA non-stop departing at 10:25am. I'll be in FCO until that morning, and the earliest AZ flight gets into MXP at 9:40am. I'm not checking bags & the flights are in the same terminal (will have to re-clear security, though). This is my first time to MXP. Will 45 mins be enough? Is online check-in possible on UA from MXP? Many thanks in advance!
