Grounded flights at Gatwick meant passengers to Glasgow were forced to shell out hundreds of pounds to make alternative travel arrangements on Thursday.

More than 100,000 people have been suffering travel chaos after drones were flown around Gatwick Airport, forcing bosses to cancel outbound flights and re-route arrivals.

Around 750 flights were due to fly in or out of the airport on Thursday but the runway remained closed after drones were spotted nearby.

Among those attempting to fly out of the London airport were passengers bound for Glasgow, forced to travel on crowded trains and drive overnight to reach Scotland.

Anna Lennon, 31, is a teacher currently living in Crawley, near Brighton who was due to fly to Glasgow on Thursday evening.

Due to the drone disruption, Ms Lennon and her boyfriend, who were returning home to Glasgow for Christmas, were forced to drive the 10 hours to the city.

She said: "Our flight was meant to be just after 8pm but the status changed a few times.

"We thought that we might chance it but we started looking at routes for driving up.

"Trains were £180 to get up so I'll be driving up. It's nine or 10 hours in the car.

"We are both teachers and this was the first day of our Christmas holidays. Total nightmare."

Others, travelling to Glasgow for work, were also caught up in the chaos.

Julian Amoah is part of a performing troupe who had been booked to play in Glasgow on Thursday night.

The 33-year-old's flight was due to arrive in Glasgow at around 11am but he did not get into Central Station until after 3pm.

He said: "One of us got to Gatwick and told us what was going on. Our client up in Glasgow had to book us a new train.

"We are only here for the day and were meant to fly home, but we don't know what is going to happen.

"Now we only have an hour or so before we start work and we have to find our way.

"It was just a long and uncomfortable journey."

Bosses at the airport have said there is no indication of when it could reopen.

Glasgow is one of eight other airports across the UK and Europe to which flights have been rerouted as a result of the interruptions.

The British Army have now been drafted in to assist with the situation ahead of the busy festive period, with nearly three million passengers expected to pass through Gatwick by January 1.

Police have said they did not want to shoot the devices down because of a risk of stray bullets.

However, local officers reinforced that there was nothing to suggest the drones were terrorism related.

It is illegal to fly a drone within 1km of an airport or airfield boundary and flying above 400ft is also banned.

Experts have suggested that the drones, which have been seen on the site since 9pm on Wednesday, must have been modified due to their long battery life.
