The flyer seminar is really really really helpful! I went around two years ago, I walked away knowing which schools I liked and which I did not, the costs involved per school, best way to get a type rating etc... Plus just the fact of going to Heathrow and seeing/hearing all those wide bodies flying over your head will give you a huge boost to crack on and start training!
P.S. British Airways is also ‘BAW’ using the ICAO 3 letter airline code
