Jet2 has moved to make passengers aware of a two-day rule.

The major airline states in the Frequently Asked Questions section of its website that it "always aims to operate our flights at the scheduled time of departure".

However, Jet2 added: "Sometimes we may need to make changes or provide alternative carriers or aircraft and cannot always notify you of this in advance. We may also alter or remove the planned schedules as shown on your booking confirmation."

The guidance acknowledges that Jet2 does not wish to cause inconvenience to any passengers, though "unfortunately sometimes changes to scheduled flight times may be required for operational or technical reasons outside our control". Jet2 confirmed that in such situations passengers will receive as much advance warning as possible.

Travellers flying with Jet2 are encouraged to frequently monitor their email and text message inboxes, as these are typically the methods used for communication if necessary. Jet2 added: "Please contact us if you change your email address or mobile number so we can update your details.

"From the Manage My Booking section on our website you can see your booking summary, request a further email confirmation or select a different email address."

Jet2 is also reminding passengers that they have an obligation to review their flight summary during a two-day period.

Jet2 said: "Please be aware that it is one of our Terms and Conditions that you re-check your flight summary 72 to 24 hours before departure."

The travel operator also continues to urge passengers to check the "latest travel information" on its website no fewer than 12 hours before departure to ensure they remain fully informed.

The airline's guidance states: "Please check this section of the website at least 12 hours before your flight for the latest flight information.

"Further information can be found by using the [above] search panel by entering your flight number or route. We recommend arriving at the airport at least 2 hours before your scheduled departure time.

"Please remember - check-in desks close 40 minutes before this."
