Having originally announced the initiative in April, the airline has confirmed that the fare would be available on its long-haul services from London to Austin, Boston, Delhi, Denver, Dubai, Hong Kong, Oakland, Philadelphia, Punta Cana and Singapore.

The fares will cost up to £60 less than the standard fare, with London to Dubai being the cheapest as it starts at £143 while Austin, the most expensive, leads in at £246, making it the most expensive. Both prices are for each way flights and based on a return trip.

In return, travellers will be allocated their seats and will only be able to take two pieces of hand luggage on board.

However, should they wish they can pay to add in either option, while executive club privileges will exist as normal.

BA chief commercial officer Adam Daniels said: “We know that when our customers travel with us their needs vary from trip to trip – some will be flying on business, some for leisure, some will be on short hops, others will be longer stays.

"We need to ensure that the fares we provide reflect those differing needs so customers can select the best option for them on that occasion.

“Someone travelling for a short meeting or leisure break, who isn’t planning to check in a bag and is happy for us to allocate them a seat, will appreciate the option to secure a lower fare.

"They’ll still receive our generous hand baggage allowance, a seat allocated to them in advance, complimentary food and drink, in-flight entertainment, blankets and headphones, all at no extra cost.

"And those looking to make even more savings can use Avios towards the flight too."
