Hi everyone,
I am not a promoter or something, no need for that. But if you are going to go from A to B (may be via C and D) you might find that useful to know what documents you will have to have with you. IATA (International Air Transport Association) a few months ago launched a website for consumers: www.iatatravelcentre.com where you will be able to know everything regarding documents you would need to have with you in your travel time.
Cheers,
Mikhail
