I've booked an intercontinental United Airline flight to the US for me and some friends of mine. The UA site requires to enter the date of birth and the gender of all the passengers, specifying that due to TSA requirements they should match those reported in the passports.
Now, indeed, I've checked several times the details before booking but, indeed, I'd like to recheck them again. However, I can check and modify my date of birth from my account, but there seems to be no way of even reading the other traveller's details to check that everything is correct.
Would it work to tell my friends to create an account on the UA site and then associating the booked flight? Should I wait until check-in? Is there any other way?
