Those are interesting adds. Suggests that VS are investing in new routes outside their traditional USA routes. I think they are good additions. With strong VFR and good business ties between Pakistan and the UK they seem sensible bets for early demand recovery. Less positively, the market is quite price sensitive, well served via the Middle East and TK and I think the VS brand might not be a 100% fit for the market. In any case, I think these are simultaneously sensible and brave choices for the airline.
I imagine they might get some transfers from the US too, in the future.
