take your passport
How to do board an aircraft with a CA connection w/o your passport??
IMO, you need to show your passport in order to get a bp. I cannot imagine how you manage to keep this secret??
ps Reminds me of a funny story, I was on a group bus from Vienna to Brno just after Schengen was implemented. A dude (from Brussels, as I recall) says I did not know I needed my passport! Needless to say, he left the bus @ the SK border. A victim of his own stupidity!
