Did anyone get through with little/no flying experience (a couple of trial flights)
I got through with a little (~5 hrs) flying. As previously has been said, it's definitely not just about flying (although when I applied first time around I had zero hours and I would definitely advise getting
some flying as at least you can say you enjoy it!). My interview and application were very much focused on my different life experiences and other soft skills which they are definitely looking for.
Remember, BA are putting us through this to train us, they know they aren't taking on experienced pilots so don't splurge on a PPL just to make yourself a 'better' candidate, get some life experiences instead.
