My CO flight from FRA scheduled to arrive at 530P and I'm booked on a 7:15 PM CO flight to SEA. Is this possible, or should I try to change to the 920PM SEA flight now? Planning carry on only (assuming not forced to bag check) and have Global Entry.

(Flights on May 28. Right now lots of availability on the 920PM SEA flight so maybe that could be a back up?)
