You have chosen a seat close to an emergency exit door.

In the unlikely event of an evacuation you will be expected to assist in the opening of the emergency door.

In accordance with CAA requirements, the following categories of passengers cannot be allocated an emergency exit seat:

Children under 12 and infants.
Passengers who are unable to reach, open, lift and throw out the exit door in an emergency.
Passengers who because of physical stature, age or sickness have difficulty in moving quickly.
Passengers who are unable to understand and carry out instructions given in English.
Passengers who are travelling with anyone who would require their assistance in the event of an emergency.
Passengers who are either substantially blind or substantially deaf, to the extent that they might not easily understand printed or verbal instructions given.

If you do not meet the criteria you will be moved to alternative seat.
