What are my rights if flights are cancelled and holidays disrupted due to fuel shortage?

Iran war and EU’s new entry-exit system could lead to travel misery this summer, but there are ways to mitigate it

Can Europe avoid a summer of travel chaos?

The war in the Middle East has prompted fears that potential shortages of jet fuel could result in flight cancellations this summer and warnings that holidays could be severely disrupted.

Airports have said jet fuel could run short within three weeks as a result of supply problems after the strait of Hormuz was effectively closed when war broke out at the end of February.

Meanwhile, longer border checks across much of Europe for Britons and most non-EU nationals has led to long queues at passport control at some airports, causing some passengers to miss flights.
