The failure of Flybe in the early hours of this morning has left many passengers high and dry - unable to get to their original destinations, or in many cases with no way of getting home from where they had travelled to.
If you are one of those who has a Flybe ticket for today or the coming weeks or months, here is the current advice.
SHOULD I GO TO THE AIRPORT?
The first bit of advice being offered by airports and regulators, including the Commission for Aviation Regulation here, is do NOT travel to the airport.
All Flybe flights have been cancelled and no alternative services have been put in place.
So the best thing to do is stay where you are, rather than going to the airport you were due to fly from.
IS MY BOOKING NOW USELESS?
Yes, with the airline now in administration, you should take it that all future bookings will not be honoured.
I WAS DUE TO GET A FLYBE FLIGHT HOME AND I AM NOW STUCK. WHAT SHOULD I DO?
Right now the best thing you can do is start looking for an alternative way of getting yourself home.
So far, however, there is no sign of that happening because Flybe operated out of airports where in the main there are alternatives there or nearby.
Indeed in a statement the UK regulator, the Civil Aviation Authority (CAA) said, "Flybe customers are therefore urged to make their own alternative travel arrangements via other airlines, rail or coach operators."
Of course, that may yet change. So it would be advisable to keep an eye on the websites of the Commission for Aviation Regulation here and CAA in the UK for more information.
In the past other airlines have offered special low rate "rescue fares" to those who are stranded to help people get home, so watch for statements from them around that.
Ryanair said it was offering cheap fares on five UK routes to accommodate customers affected by Flybe's collapse - the routes include Liverpool to Knock, Bournemouth to Dublin, Belfast to London Stansted, Bristol to Dublin and Belfast to Manchester.
British Airways has also offered special fares to affected Flybe customers.
The UK government has also asked bus and train operators in the UK to accept Flybe tickets.
IS THERE ANY WAY FOR ME TO GET MY MONEY BACK?
You are highly unlikely to get your money back from the airline directly.
But intending passengers who had bought a ticket using a credit or debit card may be able to get their money back.
They should contact their card provider and seek a chargeback to their account, if it is possible at this point.
WHAT ABOUT TRAVEL INSURANCE?
Your travel insurance policy, if you have one, may include cover for the failure of an airline.
This is known as Scheduled Airline Failure Insurance.
Best advice here again is to contact your insurer to see whether you are covered.
Such policies may only cover the original value of the ticket, not the extra costs incurred in booking new flights.
So read the terms and conditions carefully.
I BOOKED THROUGH A CODESHARE PARTNER OR AN AGENT?
If you booked through an airline ticket agent you should contact them directly to see what they can do to help.
It is possible, according to the CAA, that they may have provided travel insurance that includes Scheduled Airline Failure cover.
If it was a codeshare flight with another airline operated by Flybe, then there is a good chance it will not fly. In this circumstance you should contact the codeshare partner.
If your flight is operated by one of Flybe's franchise partners such as Stobart Air, Eastern Airways, and Blue Islands and Loganair, then it would be advisable to contact them to confirm your travel arrangements.
MY FLIGHT WAS PART OF A PACKAGE – WHAT DOES THAT MEAN FOR ME?
If you booked your flights as part of a package deal through a travel agent or tour operator, again you should contact them.
They should be in a position to help you to make alternative travel arrangements.
