Sean Tipton of ABTA: "BA have efficient contingency plans in place for customers"
Union members at British Airways have been striking after talks to avert the stoppage broke down.
The industrial action has lasted for three days from 20 March and four days from 27 March.
This is the first walkout by British Airways cabin crew since 1997 and comes after plans for 12-day strike action over Christmas were blocked by a court injunction.
So how are individual travellers affected?
I've got a flight booked with BA - what should I do?
BA has been busy, trying to back up its promise to passengers that it will "do everything we can to protect your travel plans as far as possible".
The seriousness of the disruption has depended on how many staff decide not to turn up to work on the strike days.
Customers are advised to use their passenger reference number to check their booking on the BA website to see if their flight is still operating.
BA says it is also informing affected customers by e-mail or text, using the contact details provided at the time of booking. It is asking passengers to make sure these details are correct and up-to-date.
Some flights have been operating, but other passengers have had to fly on planes with as many as 65 other airlines.
At the moment, passengers whose flights are scheduled between 19 March and 31 March 2010 can:
• Rebook onto another BA flight to the same destination within 355 days of the original date of travel
If you booked a package holiday, then the travel agent or operator has a responsibility to provide all the elements of that package.
So customers should contact their agent or operator as soon as possible after the strike dates are announced. The agent or operator will try to find alternative flights but, if that is not possible, will refund the cost of the whole package holiday.
The Atol protection scheme run by the Civil Aviation Authority does not kick in because this is designed for when a tour operator goes out of business.
For those who booked the separate elements of their holiday themselves, the picture is slightly more gloomy.
If their holiday is cancelled, they will need to try to claim the extra costs through their travel insurance. Alternatively, if it was booked on a credit card, then they might have a claim through their credit card provider for costs of over £100.
As well as the original strike dates, more strike dates are planned for later in April.
The way BA plans to deal with the disruption has been one of the first examples of the use of text messages to keep customers abreast of how their particular flight is affected.
There are other issues related to timing.
Buying a second ticket with an alternative airline, only to find that the strike is cancelled or alternative flights found, would leave a passenger with two tickets and no right to a refund.
Anyone who tries to claim for holiday costs through their insurance, if their flight is cancelled, would need to have bought the policy and made their bookings before the strike dates were announced, the Association of British Insurers says.
The small print in the insurance documents will explain exactly what cover is offered in the event of a strike delaying or cancelling flights.
Some insurers might give some leeway, so travellers should talk to their insurance company.
If your flight is seriously delayed, it would be worth getting some written confirmation of the length of delay if you decide to claim on travel insurance.
Other airlines say that they will find alternative carriers if they have an agreement to use BA flights for connecting services.
