British Airways has apologised to passengers following a technical glitch that caused severe issues on Sunday at Heathrow and Gatwick airports.
The airline is in the process of upgrading its check-in system, but something went wrong yesterday, one of the busiest days of the year, causing severe delays.

BA says the problems have been resolved and flights are operating normally. They apologised for the delays and said it had extra staff in place to help customers.
A spokesman for the airline added: "Our IT teams worked very hard to quickly fix a short-lived problem with our check-in system."
