PHL is asking passengers to arrive three hours early for their flight, even for domestic travel.

Officials expect 500,000 passengers to come through PHL through next Tuesday. 

PHL says the earliest flights are usually the busiest flights of the whole day. 

As of Friday morning, the big board looks good with all flights going out on time, but that has potential to change this afternoon with the threat of severe weather.
