Gatwick Airport has said it had returned to "business as usual" and that it will finish its flight cap at the end of the month.
Hours after the positive announcement was made, 26 flights - 13 departures and 13 arrivals - had to be cancelled after not enough staff went in to work, the business said.
"Restrictions were put on the number of flights that can arrive into Gatwick due to late-notice staff absence in the airport's control tower," said a spokesperson for the airport.
