British Airways is offering passengers a £50 discount on Club Europe flights and a £10 discount on Euro Traveller flights.
The dual promotion will see 20,000 people receive £50 off any business class short-haul return fare and 100,000 receive £10 off any economy short-haul return fare over £100.
The offer runs from September 21 until October 5 for travel between October 1 and March 20 and is only available on flights from Heathrow, Gatwick and London City airports.
Passengers must use discount codes CLUBEUROPE50 and BAEUROPE10 when booking.
BA's terms and conditions specify a maximum of nine people per booking and only one booking per code. Only British Airways flights are eligible; the offer excludes BA franchisee, flights with Oneworld partner airlines, and flights operated by codeshare partners.
The promo appeared in a special issue of BA inflight magazine High Life that was handed out to commuters in south-east England earlier this week.
On Tuesday, BA operated its first refurbished B747 between London Heathrow and New York JFK (see news, September 16).
