Moving to aviation, again, this SI is welcome. On my return from a visit to Africa at the end of last week, I had to be rerouted via Doha. I was struck that, when catching my flight back to London, I walked past a long queue next to the departure gate for the Qatar Airways flight to London, going from Doha to Moscow. Given that Qatar is a key partner of British Airways, it is still very easy if you are an enabler to have a very comfortable business-class route on British Airways through a partner airline to Doha into Moscow. I wonder whether the effectiveness of our sanctions regarding airspace could be enhanced by indicating what connecting flights and partnerships for airlines would be affected by this.
