This tool is making me crazy.

My painstakingly designed original itinerary was a LONE4: GIG-SCL-AKL-BNE-NOU-SYD-MNL-KUL-KTM-HKG-PEK-OVB-LBD-DME-GYD-LHR-GIG. I ran it through the website and after inputting my credit card details I got the dreaded 15012 error message. After reading this forum, I found out that this error occurs when the tool uses AA to book the ticket although the first flight is with another company (in this case, LAN).

I then redesigned the itinerary to get rid of this first LAN flight. In the process the itinerary became a LONE5 because I included the US, although had no original intention to visit the country in this trip. Of course the trip became more expensive, but I figured out it would be worth at least being able to book it. I had been trying to buy the RTW ticket for ages, and that was that.

So my itinerary 2.0 became GIG-DFW-HNL-SYD-NOU-BNE-AKL-KUL-KTM-HKG-PEK-OVB-LBD-DME-GYD-LHR-GIG. I ran it through the website and of course I faced another bug. This time the error message was:

We are having difficulty accepting the credit card details provided. Please validate and try again. This may be due to an invalid credit card type, in which case please provide another one (4613 - 201)

The credit card is indeed valid.

Now I don't know what to do. I want OneWorld to have my money but they seem unable to take it from me.
