At 19 i'd say leave it five years before you get to job application time and then don't mention it as you don't have to.
To be honest you are more likely to get a job at 24 than 19/20/21 (howls of protest from them that have) because really you have a bit of growing up to do yet and thats probably best done outside of the airline pilot role.
Good luck, its happened to many better smarter men than you,
Cheers
