DONE4 validation please
 

I believe my proposed re-worked DONE4 is valid, but would appreciate the advice of greater experts:

NRT-DFW-TPA (all ready flown)
TPA-XXX-BOS (stopover)
BOS-XXX-TPA (stopover)
TPA-XXX-LHR-NBO (stopover)
NBO-LHR-FRA (stopover)
FRA-LHR (stopover)
LHR-PRG (stopover)
PRG-LHR (stopover)
LHR-HKG-BKK (stopover)
BKK-HKG (stopover)
PEK-NRT

I'm especially unsure of my self on the last part - the HKG to PEK open jaw counts as one segment and one stopover?

The stops are all pretty much for business, so no optimization really possible, but I want this ticket re-issue to be the final one if possible.

Nearly all the cases reviewed here in the past support the idea that HKG//PEK is one stopover, but there have been some rare cases where the airline insisted both ends of the open jaw are stopovers, so expect approval but prepare for an argument.
