Hundreds of flights have been cancelled on Monday after the UK's air visitors management programs have been hit by a serious technical fault - with 1000's of passengers stranded.

And amid concerns that disruption could last well into this week, Britons caught overseas - and people planning to journey within the coming days - will wish to know what their rights are.

There's good news and dangerous news. While you are entitled to some assist, airways do not need to supply compensation for delays and cancellations as a result of these technical faults are labeled as "extraordinary circumstances".

Impact could last for days - live updates

Airlines do have an obligation to maintain passengers snug within the occasion of a "significant delay" - with the Civil Aviation Authority setting out a transparent definition of what meets this threshold.

You'll qualify for assist if a short-haul flight below 932 miles (1,500km) is pushed again by two hours. This rises to 3 hours for journeys as much as 2,175 miles (3,500km).

For long-haul flights going any additional than this, 4 hours or longer counts as a big delay.

This applies to all passengers flying from a UK airport, returning to the nation on a British or European airline, or arriving within the EU on a UK provider.

What am I entitled to?

In the occasion of a big delay, airways should give passengers:

• An inexpensive quantity of foods and drinks• Refunds for the price of two free telephone calls, faxes or emails• Accommodation for passengers stranded in a single day• Transport to a lodge - or their residence

Of course, when there are hundreds of passengers who need assistance, airways could also be unable to organise this assist in a well timed method.

Because of this, the Civil Aviation Authority says affected customers have the correct to make their very own "reasonable" preparations - however they need to maintain receipts with the intention to be reimbursed.

"Reasonable" is a key phrase right here, and also you won't obtain full compensation when you e book a five-star lodge or have alcohol along with your meals.

Will I get compensation?

This is the place the dangerous news kicks in.

Usually, airways do have to supply compensation if their flights arrive three hours late - however air visitors management issues do not rely as a result of these technical points aren't their fault.

And when you comply with journey on a later flight, the airline is now not obliged to supply meals, drink or lodging whilst you wait.

Thankfully, you might be entitled to a full refund when you resolve to desert your journey after 5 hours of delays.

Transfer passengers who find yourself lacking a connecting flight as a result of their first aircraft was delayed are entitled to a service again to their unique departure level.

But issues get a little bit extra sophisticated for passengers on bundle holidays - particularly in the event that they resolve to not journey on a delayed outbound flight.

The CAA's steerage says: "You may lose your holiday too, so we recommend you contact your package organiser or the airline for further information.

"If you continue to wish to journey then your airline should get you to your vacation spot. You may need to be affected person whereas they rearrange transport and rebook passengers, however the legislation says they need to get you there."

Many travellers find yourself reserving their flights, resorts and excursions individually - and when you're unable to cancel your lodging or actions, you might be able to declare again in your journey insurance coverage if it is a complete coverage.
