Flying on SW mid week out of PHL with a 7am flight. Wanting to know if the lines at security is back to pre Covid levels. Thinking that we should be there around 430 - 500 to check bags. Last time we flew the line was all the way back to the baggage claim elevators. This was pre Covid so it was a while ago. Also do they still bring the dog out to sniff the line so you can leave your shoes on?
