Several users took to Twitter to post about the issue, to which the ICAG-owned airline replied that they were working to resolve it.

British Airways' operations system was affected by an IT collapse, which caused the cancellation of at least 50 flights, according to a report by The Independent.

British Airways did not immediately respond to a Reuters request for comment.
