Monarch Airlines

Monarch Airlines, simply known as Monarch, was a British charter and scheduled airline founded by Bill Hodgson and Don Peacock and financed by the Swiss Sergio Mantegazza family. The company later became a low-cost airline in 2004 before abandoning charter flying completely. The airline's headquarters were based at London–Luton, and it had operating bases at Birmingham, Leeds/Bradford, London–Gatwick and Manchester. When Monarch entered administration in 2017, it was the biggest airline collapse in UK history up to that point, leaving nearly 100,000 passengers and holidaymakers stranded. However, on 23 September 2019, Thomas Cook also collapsed, leaving 150,000 people stranded, and went on to become the largest UK airline ever to collapse. The airline held a United Kingdom Civil Aviation Authority (CAA) Type A Operating Licence. This licence allowed Monarch to carry passengers, cargo, and mail on aircraft with 20 or more seats.
