Great tool thanks! ^
Actually seems to have highlighted a problem with my itineraryt - I used my current DONE4 itin (ticket issued and started) as an example.
I have LHR-VCE-LHR in the itin - that seems not be a direct flight (any more?).
I am sure I looked this up as a BA flight before booking - was I mistaken or has VCE changed to only being serviced out of LGW?
