I know the answer to that question all to well. The answer is BAD THINGS

Good point about the Sabre thing. I am not too sure what BA uses but I do remember talking about splitting the ticket in LHR. She even showed me where she did it in the fare calc.

Here is what AA told me about more than 16 segs. If you try to print more than 16 ses by spliting the fare, you can get double charged. For example, a 30 seg ticket costs $6000 total. If AA tries to split the ticket into 15 segs of $3000 each, your credit card may get charged $6000 twice. I was then informed by 3 people that it may take 6 months to have the billing reversed.

As for splitting the ticket after it has been paid for, AA did that too. The MIA airport ticket counter spent 1 hour typing in the 4 segs I needed changed, 1 hour getting someone to refare it and 6 hours trying to print it. Eventually they split the ticket and the fare calc was non existent. The restrictions box said "RTW 17 segs." They were clueless.


Now BA did fine. They split the ticket and had the fare calc put in within an hour all three times. They were on top of things and worked hard to make things easy. FYI...I used a CTO in London, LHR airort, and BCN airport for the BA changes.

In retrospect, I would stick with BA all the way especially if it is complicated.
