BA pilots announced three days of strikes – taking place on 9, 10 and 27 September – in a dispute over pay.
Despite the first strikes being on 9 and 10 September, some customers flying between the 8th and 12th have been told their flight has been cancelled – and to rebook or get a refund.
One customer said their flight on 25 September had also been cancelled.
Many people have said they have been unable to get through to BA to make alternative arrangements.
BA says it carries 145,000 customers every day – with a fleet of more than 280 aircraft – and a BA plane takes off from somewhere in the world every 90 seconds.
BA said in a statement: “We are doing absolutely everything we can to prevent this unfair action from taking place and ruining our customers’ travel plans.
“Airlines have a very complex operation and during times of widespread disruption, there can be knock-on effects onto flights on other days.”
Customers have reported receiving emails late on Friday night and in the early hours of Saturday morning informing them their flight had been cancelled.
Many have taken to social media to complain that they have been unable to rebook via the website or get through on BA’s phone lines.
Abby Deem, 32, from Cambridge said her honeymoon plans had been “ruined” after her business class flight to Mauritius on 9 September was cancelled.
“We’ve been looking forward to this flight for a year,” she said.
“Neither of us have ever had the luxury to travel business class, and after the wedding it seemed the perfect way to start our honeymoon.”
She said she felt sick when her fiance Jonathan got a text to say the flight had been cancelled.
They have now booked economy flights with Emirates and they estimate it will cost them an extra £500.
Jennifer Bond, from Manchester, was due to fly to Las Vegas with her fiance Simon to get married but their flights to and from Las Vegas (11 and 25 September) have been cancelled.
She said: “Nearly two years of saving up and budgeting relentlessly and this happens three weeks before we fly.”
It was “impossible” to get through to BA on the phone, she added, so they have booked new flights with Virgin – costing £700 more than their original flights.
“We’re now out of pocket and the time to process a refund is four weeks,” she said. “It’s disgraceful.”
Another customer, Anna Redding, was scheduled to fly to Nairobi with her partner for their honeymoon on 11 September and return on 27 September – when the final strike is scheduled to take place.
They received an email saying their outward flight had been cancelled, and their return flight had been delayed.
She said they had also saved up to upgrade to first class flights as it was a “once in a lifetime” holiday.
They have been unable to get through to BA on the phone and she said the advice is unclear, adding: “Do we try to get another flight with someone else but lose the first class or do we wait just in case but risk not getting any other flights?”
The company’s Twitter feed was inundated with messages from frustrated customers, with some saying their cancelled flights were still on sale.
In response to one customer, BA said some flights before and after the strike were “still subject to disruption due to operational reasons, including crew rostering and positioning of aircraft”.
Travel expert Simon Calder explained it had turned into five successive days of cancellations because BA would not send a flight to, for example, Hong Kong, if a pilot was going to go on strike the next day.
He also said BA has to find customers “an alternative flight on the same day if it possibly can, even if it means buying you a ticket on another airline”.
If you are delayed overnight, he said BA has to pay for a hotel and meals.
He added: “The worst thing you can do is take a full refund because then you will be buying another ticket yourself and that could well cost more.”
The British Airline Pilots Association (Balpa) said on Friday the strikes were a “last resort” born out of “enormous frustration” with airline management.
Pilots have rejected a pay increase worth 11.5% over three years, which the airline put forward in July.
What can I claim if my flight has been affected by the strikes?
If your flight has been cancelled because airline staff are striking, the the Civil Aviation Authority said, then this would be considered within the airline’s control, and therefore you have a legal right to either:
- A full refund, and this includes flights in the same journey that might be from a different airline (for example, an onward or return flight)
- A replacement flight to get to your destination
- Or, if you are part way through your journey and don’t want a replacement flight, you are entitled to a flight back to the airport you originally departed from
In some cases, passengers may be entitled to additional cash compensation for the inconvenience – but only if you receive notice that your flight is affected less than 14 days before departure.
