Leave plenty of time for connecting flights especially domestic to international! Absolutely the most confusing and bizarre airport I've ever encountered.
Watch out if TSA checks your bag. They throw everything into a pile and when you tell them to repack the bag they continuously ask "ma'am are you sure you want me to repack your bag" so lazy...
DeltaAirlines has been a dependable carrier. In the years I've flown I've not had a single bag lost and have experienced few delays. Fly like the pros, fly Delta.
