I have to book an upcoming flight. With all the 1-stop flight these days, what is "too short" of a layover? I see a lot of +/- 50 minute layovers, with a plane switch. Is this cutting it too close to make the 2nd flight? My husband really doesn't want the 50 minute layover, but I don't want the 2+ hour layover! What's better? Thanks, everyone!
