From what I have understood, you will need to apply and be approved for the loan without any assistance from easyJet. This involves putting a business plan together and sourcing some form of security (e.g. a house). Then if you are deemed exceptional, easyJet will offer to underwrite the loan with their head office instead of whatever you used originally (presumably your parent's house). That being said, I wouldn't rest your hopes on being offered an underwriting
That doesnt sound quite right - wouldn't that defeat the object of underwriting loans in the first place? If only people who can (and are willing) to source the loan anyway can get it then that's great for them but it doesn't do anything to boost accessibility
