so... a bit more time. checking some widebodies:
A300/310: width alright: HD 9, Std 8 (not sure hte A300 is certified for 9 abreast, but the 330 certainly is)
A330/340: looks alright. 500/600 now has nice space for those biz seats finally.
A350: 9 abreast in Std sounds ok, 10 abreast in HD... they really want to do that on premium airlines now. crazy sheep sitting down there. but looks alright
B767: looks ok. 8/7/6. 400 has not much space to include the seats though.. only get to 329 in reasonable 30" std (which is probably rather realistic though

)
B777: looks ok: 10/9/7. floor area seems ok. X is a bit wider interntally, 10/9/8
B787: 9/8/7 - seems ok. the -3 has now the usuable -8s-area
L1011: 9/9/7 - looks ok.
DC10: 10/9/7 - width alright. length: -30ER seems to lose a lot of seats though (thought its the same size as the -30)!
