All of the longest nonstop British Airways Airbus A321 flights are scheduled to depart from London Gatwick Airport. Whereas London-Heathrow is BA’s mainline international hub that attracts many of the world’s widebody aircraft, Gatwick is the major hub from where BA operates many of its leisure flights. Most of these flights are operated by British Airways’s subsidiary, BA Euroflyer with a few by the charter airline, Titan Airways. Here are all the British Airways flights over 1,000 miles scheduled for April, according to data provided by Cirium, an aviation analytics company.
