Hi,
after one flight cancellation, re-booking and name change of Berlin airport from TXL to BER there was a problem with the e-Ticket not covering the whole route so BMI fiddled a little bit with it. Now the ticket is split in two. The first part BER-FRA-JFK-SFO shows a ticket nr. like 236-XXXXXXXXXX-XX, the second part (same itinerary-Nr) LAX-FRA-BER shows 236-XXXXXXXXXX. Is this a mess or should I stay with these numbers?
