Whenever i travel international i usually have a paper ticket so i check in at the airport. this time i booked on United/Lufthansa to go to dubai through the internet on United's website, i noticed that it said that "internet check-in available for this international Itinerary 24 - 2 hours before departure time" and that you have to provide a passport number.
my questions are simply
1- is that possible, as I know that KLM/USairways/British Airways don't have that
2- If it is true Can I as an Alien Resident do that provided that i hold a non us passport but with a Valid US alien resident Visa good for 5 more years?
any help oar enlightment on this subject would be great
