"The data communication issue is resolved, and FLL has returned to normal operations," the airport Tweeted.
The airport had issued a travel advisory just after 8 p.m. about the data problem.

Greg Meyer, a spokesman for the airport, said the outage blocked data from coming into the airport and prevented passengers from being checked in. The airlines affected were Azul, Spirit, Delta, JetBlue, Emirates and United.
"If you can't check passengers in then there is a delay in the flight," Meyer said earlier in the evening. "There is a ripple effect."
AT&T worked with the airport's Information Technology department to solve the problem.
Staff from The Broward County Aviation Department was sent to the affected areas to assist passengers, Meyer said.
Though the system returned to normal operations, travelers Monday night were being encouraged to check on their flight status before heading to the airport because of residual delays.
