British Airways is holding a “Bermuda Day Seat Sale” to celebrate its centenary, offering a 25 per cent discount on World Traveller fares for travel to London later this year and early in 2020.

The sale begins today and concludes on June 6.

The reduced fares are for travel to London between September 15 and October 15 this year, and between January 6 and March 27 in 2020.

Seat sale prices include all airline related taxes, fees and carrier charges and requires a seven day minimum stay including a Saturday overnight. Flights are non-refundable, British Airways said.

Tickets can be purchased through local travel agents, by phoning the toll-free number, 1-800-AIRWAYS, or by using the website at www.ba.com.

The airline said that ticket availability may be limited during these promotional dates.

The airline celebrates its centenary on August 25, marking the 100th anniversary of the launch of the world’s first daily international scheduled flight between London and Paris by British Airways’ forerunner, Aircraft and Travel Unlimited.

British Airways says it is investing $8.4 billion over a five-year period including new aircraft, new cabins, new catering, new lounges, wi-fi and new routes.

New routes this summer from London include Kos and Prevara in Greece, Ljubljana in Slovakia, and Corsica.
