I am flying LGA-IAH tomorrow at 5:30am. I have never heard of a flight leaving that early, this is a first for me. Not to mention, its oversold and considered an International flight because we are continuing onto Ixtapa, Mexico. So, we are supposed to be there at 3:30am. LGA opens at 3:30am! This should be interesting to say the least. I am planning on getting to the airport at 4, I hope I will be OK.
