QR has also been flying to SEZ for a while. I think there was a brief break in service but it's been back for some time now.

Both OneWorld and Star Alliance have had SEZ accessible for several years now, and has gotten even easier with the addition of more carriers recently. Skyteam is the only one with an issue since the only SkyTeam carrier I'm aware of with any service to SEZ is AF but it's a codeshare on HM so can't use other airline miles.
