Did any of you happen to keep track of how long previous conversions took? It's not uncommon to switch out a cabin during C check so 92A may be getting a makeover while in XMN.
86A and 89A were flown to SBD in November and December, but I couldn't find any evidence of them being permanently withdrawn from service.

Re ORD the question is not only how many old cabins remain operational but also what are they doing with the 9 new cabins they have? To my knowledge only JFK-HND-JFK, LHR-HND-LHR, and now SFO-HND-SFO are confirmed with the new cabins come April.
