152 tonnes and a 26% load factor isn't that profitable. The whole route is completely stupid. It's a vanity route and Qatar is only flying it because of WG help. It's going to be downgraded to a 320 soon and the frequency cut. That is, if there is not a contract stipulating frequency for political reasons.
@PDXCWL45, Qatar don't exactly have an aircraft shortage, do they? Not only are they desperate to lease planes to other airlines like BA, they have lots sitting around doing nothing. They might as well fly this route because it would not surprise me if the WG is underwriting any losses or give other incentives. But we'll never know "commercial reasons" will be cited in any FoI request.
