If you need to reissue/reroute a BA issued xONEx, what's the normal practice for getting it done? Assuming a ex-CAI or ex-IST, some options seem to be to contact:

- the issuing office (CAI, IST)
- the local BA office (i.e. wherever you happen to be at the time)
- an OW RTW desk (BA don't have one, do they?)
etc.

On my last xONEx I went back to BA/CAI, but I'm not sure if this was the best plan or not. Seemed to work OK mostly, but not 100%
