Gotta be 18 by March 2024 which is very misleading as the FAQs on the Skyborne says that there will be 3 additional course starts throughout 2024 and I would be 18 by then. Also says that you can be 17 to apply on the BA website. Real bummer but there is hopefully next year.
Also told by a source they are expecting 50k applications and they're just gonna reject everyone who is still in full time education.
