It looks like the AMS-DOH flight now goes non-stop, continuing to MCT. It used to stop in DMM en route to DOH.
(The frequency seems to be five times per week. I recall that it was four times per week, then
this press release indicated that it would increase to six times per week, still with a stop, but not that it has gone non-stop, it seems like five times per week.)
Good news for those flying from DOH, of course. The stop in KSA was tedious.
Lufthansa also recently started going non-stop to DOH -- the flight used to go FRA-RUH-DOH, now FRA-DOH-BAH. The only sacrifice was a reduction in capacity from 7 to 6 times per week.
