The pilots union, Balpa, has warned prospective pilots from starting any training courses, saying they would be left with huge debts and no prospect of employment.
Trainee pilots could end up owing more than £100,000 and would not find a job to pay back loans, the union said.
About 200 trainee pilots in UK flight schools who were set for jobs with easyJet have already had their conditional offers of employment withdrawn, after the airline looked to cut hundreds of pilot jobs in the summer as the effects of Covid-19 battered the industry.
