With the changes taking place April 1st, the FAQ will need to be revised. In that spirit, I'll start off with a few amendments:
Airline leaving:
BA is selling (or has sold) some of its subsidiaries, notably British Mediterranean. The changes won't go into effect as of Apri 1st, but BA coded flights on BMed will end in at the end of the summer schedule.
Airlines joining:
- JL: JAL
- JO: JALways
- EG: Japan Asia Airlines
- JC: JAL Express
- NU: Japan Transocean Air
- ??: J-AIR
- MA: Malév
- RJ: Royal Jordanian
- 4M: LAN Argentina
- XL: LAN Ecuador
Of the new entrants, only JL has a real first class, operating from NRT to: SFO, LAX, ORD, JFK, GRU, HNL, LHR, FRA, CDG, SIN, BKK, HKG. From KIX: LHR, CDG and LAX. Much like AA's suites and coffins, there are two kinds of F on JL: the old SkySleeper and the newer and much better SkySleeper Solo. The difference between the two is similar to AA's coffins and suites, with suites being far preferable. Most of the premium routes get the Solo seat sometimes (JFK on JL 5/6, LHR on JL 401/402, ORD on JL 3/4/9/10, CDG on 405/406 and FRA on 407/408). The old Skysleeper seat operates from NRT to LAX on JL 61/62, NRT to SFO on 1/2, KIX to LHR on 421/422, KIX to CDG on 425/426 and KIX to LAX on 70/69. Note that for instance the NRT-JFK-GRU service has the old SkySleeper seat, but does have the "shell-flat" business class.
