As reported by multiple ground staff and on-board staff, UA servers at LAX completely crashed on August 10 around 2:00 PM. The result was that all passengers were required to check-in either online or on their smartphone and board with the electronic or pre-printed BP. While this was a workable solution for many domestic passengers, international passengers were left stranded. Several of us flying on the non-stop to LHR were stuck waiting in the T6 check-in area for about 2 hours while the agents tried to figure out a work around. After much shoulder shrugging, one of the agents figured out that she could call a reservation center in Denver and ask the agent to check us in by phone. The next step was to write out a boarding pass using pen and paper! While this was resolved in a matter of time, the real sticking point was that the bag match (matching of passengers to luggage) needed to be done manually since all of the computer systems were inoperable. Needless to say, a process that usually is done automatically took about three hours with all of the passengers already onboard the aircraft. When the match was finally done, we were held until the manifest could be printed in San Franciso, faxed to the UA operations center under gate 85 and then driven to the aircraft at gate 77. The scheduled 5:55 departure pushed back from the gate at 8:50 PM. Does the two hour wait to check-in and three hour ground wait make it worth my while to ask UA for some kind of compensation or should I just be happy we finally took off?
