I'm flying longhaul from HKG to Doha, then from Doha to SIN in mid April, all on Qatar Airways' new Airbus A330-200 aircraft. I will be in economy. Anyone have a seat recommendation with leg room? Any knowledge of exit row numbers or exit row configurations?

Same question here.

I will be flying CDG-DOH-SIN return and would appreciate some insight on the better seats (as well as the ones that should be avoided).

Strangely, the Amadeus seatmaps available on checkmytrip.net seem to show different configurations on the CDG-DOH, DOH-CDG and DOH-SIN-DOH routes, with rows 28 and 30 being exit rows respectively on CDG-DOH and DOH-CDG, whereas DOH-SIN-DOH have two additional rows and no real exit row.

Thanks,
Yann
