Second Passport
Airline pilots are entitled to obtain a second passport.
You will need to get a letter from your employee stating you are employed and you need a current passport to continue your duties as which they support your application for a second passport.
As I understand this cannot be done online but needs to be done using the standard form. You need to fill it in as if applying for a "first passport" with all required documentation, using the notes section to state it is for a second passport.
Send it with you letter and you should get your second passport no problem, I would also suggest you opt for the 42 page instead of the standard 36 page.
Hope this helps
