I have done a mixture of aircraft dismantling, base line and AOG work. This has covered 737,747,757,787,320/330/340 and line 380. I currently do A320 base which is the aircraft I know best. With half your modules you can look for mech work to get your OJT. This is the chicken and egg part. Can't get a job without exp. can't get exp without a job. You need to convince someone to give you a start. Base is best. Line is a live environment and without experience I doubt someone would put you on the ramp. Base is more controlled environment for you to learn. Where are you based? Lufthansa are looking for people at Gatwick and they have taken people with limited experience.
