This facility is available from 15 days up to the online Check-In Deadline of four (4) hours before each scheduled flight departure time. Each Boarding Pass must be printed and presented on an individual A4 page. No further changes can be made to passenger name(s), flight dates, times and route once a Passenger has checked in online.
6.2 An online check-in fee applies to all reservations except in respect of certain promotional fares. This fee of £6/€6 and is charged on a per person/per one-way flight basis at the level set out in our Consolidated Table of Fees. Except as provided for in Article 10.2 or 10.3 below, this fee is non-refundable.

6.3 If you fail to present a valid Boarding Pass at airport security or at the boarding gate and there is sufficient time to re-issue you with an alternative form of Boarding Pass, you will be charged a Boarding Pass re-issue fee at the rate set out in our Consolidated Table of Fees. All passengers departing from Moroccan airports must present their Boarding Pass at the local airport check-in facility.

6.4 All non-EU/EEA citizens must have their travel documents checked and Boarding Pass stamped at our Visa/Document Check Desk before going through airport security.

6.5 Any applicable Checked Baggage fees and/or excess baggage charges must be paid and your Checked Baggage deposited at a Bag-Drop desk no later than forty (40) minutes prior to scheduled departure. Standard opening of Bag-Drop desks is two hours before scheduled departure.

6.6 You must produce valid travel documentation matching the details on your Boarding Pass for all flights both at airport security and at the boarding gate.

6.7 You should be at the boarding gate at least thirty (30) minutes prior to scheduled departure. Boarding closes twenty (20) minutes prior to departure. If you arrive later than this at the boarding gate you will not be accepted for travel. For travel on a later flight, you will be required to make and pay for a new reservation.

6.8 Except in respect of passengers who have pre-notified us that they require special assistance, we do not pre-assign seats on any of our flights. However, if you have purchased “Priority Boarding”(click here for Regulations concerning Priority Boarding) and report to the boarding gate no less than thirty (30) minutes prior to flight departure you will be able to proceed towards the aircraft before passengers who have not. We reserve the right to assign or reassign seats at any time, even after boarding of the aircraft. This may be necessary for operational, safety or security reasons.

6.9 You must not carry hot drinks aboard the aircraft or consume your own alcohol on board.

6.10 You may not smoke in any part of an aircraft operated by us. Failure to adhere to this stipulation may result in severe criminal penalties being brought against you as well as all disruption costs being claimed against you.
