Loganair has been facing a high demand for changes to bookings - and now faces disruption because of changes to schedules at Edinburgh Airport on Tuesday.
On Friday morning Scotland's airline stated: "Due to the sad passing of Her Majesty Queen Elizabeth II, we expect that some customers due to travel in the next few days may wish to make changes to their bookings.
"We know at this extraordinary time, families and friends may wish to come together and reconsider their travel plans in the coming weeks.
"In light of these circumstances, Loganair is offering extra flexibility to customers with bookings for travel during this period:
"Should you wish to make a change to your travel dates(s), you may do so free of charge and move to another flight date during the month of September.
"If you were due to attend an event that has been confirmed as rescheduled or cancelled, then you may request a credit voucher for the original value of the journey by completing this form.
"Vouchers can be redeemed against new bookings made within 3 months of receipt of the voucher for future travel.
"In this instance, you will be required to provide supporting documentation of a major event cancellation or rescheduling that you were due to attend - this can be uploaded via the form.
"The quickest and easy way to make changes is online and our Customer Help Centre is extremely busy right now - so we kindly ask that you please only call us if you really need to."
And yesterday (Saturday September 10) the airline stated: "If you’re travelling with us to or from Edinburgh on Tuesday 13 September, some Loganair flights have been retimed or combined due to closure of the airport during the late afternoon to enable HM The Queen’s final journey from Scotland to take place.
"If your flight is impacted, we will email you today using the contact details held in your booking.
