I booked a round-trip airticket (China Eastern Airline) from Los Angles to
Shanghai at www.expedia.com. Their website only provides some place for you
to input your passport number, but not its issue date or expire date. Are
the issue date and expire date required for all the flights to US? I kind of
remember that US requires the airline to provide such information before at
least 48 hours before the flight? anyone has similar experience? I will
leave in two days... Thanks
