THOMAS Cook flights to and from Glasgow Airport have been cancelled after the 178-year-old tour operator collapsed.
The last of the company's flights to arrive landed at 5.50am from Orlando, Florida.
A further three arrivals had been cancelled while three scheduled departures were also grounded.
The company ceased trading earlier this morning after failing to secure a last-ditch rescue deal, putting 9000 people's jobs at risk in the UK.
The UK Government has been criticised after it decided not to bail out the troubled firm.

An estimated 150,000 tourists msut now be brought back to the UK by the Civil Aviation Authority in a flight programme costing £100 million.
Jim Hatton, a 61-year-old from Helensburgh in Argyll and Bute, suffered a "sleepless" night over fears the company's collapse would leave him stuck in Menorca without critical medical supplies.
The retired chartered engineer was waiting among huge queues in the airport for his replacement flight to Glasgow. He told the PA news agency: "My wife and I have mobility problems and take a lot of meds for pain relief and other conditions.
"We made provision for a couple of days extra but if we had been delayed longer some vital heart medication I take for an arrhythmia would have run out.
"We had plans to visit a doctor locally to try to get a prescription but we were told it would be OK."
He added: "Last night was sleepless, I was watching news feeds constantly.
"I think I fell asleep for an hour or so but I was watching all the Thomas Cook aircraft heading for the UK on the FlightRadar app knowing that an announcement would only be made once most of the aircraft were home.
"Thomas Cook staff are highly visible and helping with the repatriation process.
"One lovely lady said she has been working for Thomas Cook for 43 years. Now she doesn't know what she's going to do."
Glasgow Airport told passengers who were meant to be flying with the operator not to travel to the terminal.
All future Thomas Cook bookings have been cancelled, affecting around one million people.
Thomas Cook chief executive Peter Fankhauser said his company had "worked exhaustively" to salvage a rescue package and apologised to those impacted.
The firm's package holiday customers will have the cost of their accommodation covered by Atol.
Scottish Passenger Agents' Association (SPAA) president Ken McLeod said: "This is a terrible day, not just for the UK travel industry but on a global scale as well for the most renowned name in travel.
"The only positive that we can take from this is that it once again the situation demonstrates the importance of consumer protection, in this case the Atol scheme which ensures that most British travellers shouldn't be left out of pocket or stranded overseas."
