British Airways has put one million seats on sale for under £35 each-way as part of a four-day flash sale.

The fares included are for travel up to the end of March and are included in BA’s flexible booking policy offering no change fees or a voucher exchange.

Seats are available across routes including to Athens, Bologna, Copenhagen, Dublin, Glasgow, Milan, Venice, Newcastle and Naples. They must be booked by September 22.

Club Europe fares to 60 routes have also been reduced, with return tickets to Dublin at £119, to Krakow at £129, Prague and Vienna from £149 and Nice from £169. These must be booked by September 30.

Andrew Brem, British Airways’ chief commercial officer, said: “It is exciting to be able to offer our customers a great range of low fares on travel to a large number of short-haul destinations, alongside our impressive sale prices. Travellers can book with absolute confidence knowing we are operating with stringent safety measures in place and that should anything crop up they can change their plans incurring no change fees, thanks to our flexible booking policy.”

British Airways is currently in the middle of a September Sale, with discounts on flights to New York, Antigua, St Lucia and the Seychelles.
