The QMMF (Qatari motorsports federation) and the Lusail International Circuit issued a Q&A (which I did not receive, but Reuters did) stating that despite the cancellation of the FIA WEC round at Qatar, they are still planning to host MotoGP and F1 at the circuit. Preparation is going ahead as normal, and the airport is functioning at 100% capacity.
At Aragon, I asked senior officials off the record what the status of Qatar was. They told me, still no decision been made about it. There were rumours that it had been cancelled already, but those rumours were based on the idea that Austria had issued a travel ban for Austrian citizens to Qatar. That is false. Austria has Qatar as a code yellow - travel, but be aware and take precautions.
So, for the moment, looks like Qatar is on. But that could still change in the next couple of weeks. I expect a decision before MotoGP heads off to the flyaways. The teams have to know by then just because of the logistics involved.
