British Airways said it had resolved an issue with its systems that affected the check-in process on flights from Heathrow on Wednesday, saying that customers were now being processed as normal.
"Customers are being checked in as normal after an earlier problem was resolved. We are sorry for the temporary check in problems which caused some delays for our customers first thing this morning," British Airways said in a statement.
"This issue is now resolved and our staff are working flat out to help customers get away on their holidays."
