Spirit Airlines issued an apology after putting a six-year-old unaccompanied minor on the wrong flight.

The child was set to fly on Thursday from Philadelphia International Airport to Southwest Florida International Airport in Fort Myers, Florida, to visit his grandmother, WINK-TV reported.

Instead, the boy was “incorrectly boarded” on a flight to Orlando, Spirit acknowledged in a statement on Saturday.

The statement did not address how the error came to take place - during a busy holiday travel day.
