PHILADELPHIA (CBS) — Pent-up travel demand has led to a parking shortage at Philadelphia International Airport, and officials are warning that parking spaces are full. The parking shortage at PHL surprises many passengers as they prepare to leave town for the busy Easter travel weekend.

The airport said Wednesday morning that all five of its parking lots were full. This includes 12,000 parking spaces that are no longer available.

In addition, the airport has a budget car park with 7,000 parking spaces, which was very popular, but has been closed for two years due to the pandemic.

Airport officials say parking demand dropped to zero at that time because people did not feel safe flying.

It was costing PHL several million dollars to run the economy lot shuttles at the airport, so they made the decision to close it.

Part of the economy lot which includes 2,000 parking spaces will reopen on Thursday next week, but it won’t be in time for Easter.
