Got it!
Just booked it! For ALG you can transit through the airport without needing a visa, you need your onwards ticket but and no Israeli Stamp or Passport. I have a friend in Algiers, maybe I will go there earlier.
The ALG_DOH leg is in Business, but the seat they assigned me is 2A, from the cabin map is actually a First Class seat (on a330 and a340), sadly I will not get First Class lounge in DOH then.
Is somebody doing this trip on the 3rd of February or returning on the 8th of February? Could be fun to spend some time chatting about miles!
