Our flight is scheduled for 6:30 a.m. - is Islip open before 4:30? According to Delta's website, this is considered "peak" time for Islip. Will 4:30 be cutting it close?
I have a 6 am flight in 2 weeks. I stopped at the Delta counter and they advised to come in 2 hours before. They sais there are long lines even at that time of day and yes, they are open.
