I think you'll just have to wait until travel is over, because this is a "one in a million" type of situation. Just make sure you have all 3 ticket receipts.
Actually, it might not be "one in a million." Is the ticketing sequential, i.e., segments 1-4 on ticket 1, 5-6 on 2, and 9-10 on 3? E-tickets are limited to 4 flight coupons each. The "one in a million" is if, i.e., segments 1,2,5,6 are on ticket 1, and 3,4 on 2.
