You might have aircraft changes on DOH-EVN. You wouldn't have any guarantees regarding which A320 configuration you'll fly on.
ARN was A319 in the early days of the route, but yeah I think it would be pushing the A320 a lot. QR did start HEL with A320, which is in GC measure is 150 or so miles shorter than ARN.
