Thinking about heading to Vegas in July after a few days in Maine. Leaving aside the insane cost of the flights, I'm trying to figure out the best way to get there. There are no direct flights between PWM and LAS and I'll either have to layover in Philly or DC. Is a 50 minute layover in Philly too risky? Should I play it safe and book flights with a 2 hour + layover? Never flown in/out of Philly so I don't know if its an airport known for delays. Any suggestions are much appreciated.
