Don't know how much of this is accurate but if it is all correct I think it is all summed up here:
'Longhaul
BA drops BA17/18 LHR-SIN-MEL with the flight becoming a LHR-SIN terminater operating as BA11/12.
The JSA is modified to include QF29/30 (BA7317/7318) MEL-HKG-LHR to enable BA to still offer twice daily LHR-MEL through codeshare, though at present the LHR-HKG sector is not codeshared (Any plans for BA/QF to modify the JSA to include HKG with SIN and BKK?).
PEK does indeed increase to daily. Interestingly some flights also offer First, as previously all PEK flights were operating with a three-class service only.
MAA stays 6xWeekly, while BLR stays 5xWeekly, both with the 777. BA had indicated both flights would go daily in summer 2006, so either yet to be loaded, or being delayed until the Winter.
ISB is indeed upgraded to a 744 again, after a couple of years operating with the 777.
BA66/65 LHR-NBO is downgraded from a 744 to a 777, with the 3xWeekly BA89/88 staying as a 763.
BA137/136 the 3xWeekly LHR-LOS service switches from a 777 to a 763. BA75/74 remains a daily 744.
BA243/242 LHR-MEX sees its seasonal increase from 3x to 4xWeekly with the 744.
BA2233/2232 LGW-BDA becomes a daily service with the 777, up from the 4xWeekly service this Winter.
LGW-IAH becomes twice daily, up from last years 13xWeekly, both flights operating with the 777. BA295/296 continues to operate too with the 777, routing LHR-ORD-IAH.
BA2227/2226 LGW-ATL is now scheduled for three-class 777 service on some days - I guess the premium loads are not there?
BA229/228 LHR-BWI and BA203/202 LHR-DTW both stay as a 767 this summer.
BA217/216 and BA293/292 LHR-IAD are 744 for the summer peak, with BA225/224 the daylight flight being a 777.
BA69/68 LHR-PHL is switched from a 777 to a 763, while BA67/66 remains as a 777 (No 744 for PHL this year).
LHR-EWR is seeing a lot of 767 activity from BA in place of the 777s used at present. BA185/184 operates with a 767 on Monday, Saturday and Sunday and a 777 Tuesday through to Friday. BA189/188 operates with a 767 on a Saturday, a 777 the rest of the week. BA187/BA186 operates with a 767 Monday through to Friday (return flight is Tuesday through to Saturday morning), while the Sunday flight (return Monday morning) is a 777. Interestingly, this means three BA 767s will be in EWR on a Saturday (BA186 am departure, plus the two arrivals from LHR). Guess BA isn't getting the yields in F on this route to be using the 767 so much.
LHR-JFK sees all 744 service except for the daily BA113/116 flight which is a 777 (JFK currently gets the 777 twice daily).
LHR-BOS sees twice daily 744 on BA213/212 and BA215/214, while the daylight flight BA239/238 stays as a 777.
LHR-ORD stays three times daily, BA295/294 continuing to IAH, while BA297/296 is upgraded to a 744.
LHR-LAX goes 3xDaily again this summer with the return of BA279/278. All flights are operated with the 744.
LHR-SEA goes to 10xWeekly for the summer, all 744 operated flights, with BA53/52 operating on Mondays, Wednesdays and Saturdays alongside the daily BA49/48.
LHR-YVR goes to 13xWeekly, all 744 operted flights like SEA, with BA87/86 operating every day except Wednesday alongside the daily BA85/84.
LHR-YYZ goes 3xDaily, with BA92/93 and BA98/99 operating with 777s and BA96/97 with a 763. Initially one of the 777 flights had been down for a 744, which would have been great for the people at YYZ to view! BA also seems to have addressed the timings, with deaprtures from LHR at 11:55, 15:10 and 17:30 and return flights from YYZ at 18:15, 19:55 and 23:45.

KJ is also due to receive an additional Airbus A321 in June, so guess we may see frequency increases on their routes, though nothing announced yet from what I can make out. (An additional A321 due in Feb too, though this will replace A320 G-MEDA)'
