This statement was retweeted by the Philadelphia International Airport's Twitter account.
The airline also posted that flights were still departing, but customers traveling may experience delays or cancellations.
By 2:30 p.m., JetBlue said power had been restored, and its systems at the terminal are back online. Customers should now be able to book flights on the airline's website and check-in for flights.
The airlines website, jetblue.com, was down during the outage, but it's now back up.
