Of course! Sorry Serfty you already told me in this
thread back in Jan but I forgot. Btw I assume you meant "TC1 (Americas)".
Calling the agent back tonight....
Work has been hectice and I finally called the agent back last night. Some more lessons learned... (see below)
I first explained that according to the technical sheet, there should be no charge. After putting me on hold for aournd 5 minutes, he came back confirming that (woohoo!), but also indicated that if the re-routing requires a ticket re-issue, then it requires a ticket re-issue fee (same cost, doh!).
I went ahead and change the routing as I suspect it would be similar in cost. However due to the new routing, I could no longer confirm the exact dates of my last few legs. Surprisingly, he was able to leave these legs as Open - I didn't realise they could do that.
I was futher surprised when he offered to contact the fare calculation desk and gave me the total difference over the phone. Last time they fob me off and ask me to call back in 24-48 hours. After another 5 minutes on hold he came back with the figures.
I accepted it and immediately asked for the seats to be assigned (from lessons learnt last time). Will call Japan and pay for the difference come Monday.
Here's another question... I understand DONE4 is a 1-year ticket. But is it 1-year from ticket issue, ticket re-issue, or commencement of travel?
