I'm taking a group of students from SFO to Rome in January. We are booked on Delta, originally through ATL as I thought we would have less potential weather delays. Well, Delta canceled the ATL to ROM flight for that day and now we are through JFK. I can keep it JFK, or switch to the day before to be back through ATL.
I've never flown Delta and never through either of those airports (I live where the airports don't ever have to shut down for weather!). Any recommendations?
