BA b2b's are quite costly for the company, but do make scheduling slightly easier. It would appear that talks are ongoing as to whether scrapping them would cause other problems, but initial data does not point to any immediate decision. Over the last 5 years the cost of crewing the daily East coast b2b operation has increased considerably. Scrapping them will provide serious savings in terms of finances, accommodation and out of hours agreement/limitation "headaches".
Another area being looked at is MBTs and counting the day of arrival as the 1st MBT - except for arrivals after midday.
Optimum use of longhaul a/c is equally being monitored, with for example the JNB likely to go a 4 day trip - daylight return. It has already been announced that BA is to withdraw from MEL, with the ONEWORLD alliance being central to the future changes in the BA network, ie if X airline can do the route on BA's behalf, BA can serve another destination without having to invest in more a/c.
What should be noted is that numerous "crew saving" initiatives are taking place behind the scenes, with the LGW - One Fleet announcement being the first ready for formal consideration.
Crew will also be aware that the move to T5 will impact on certain areas of the current agreements, in BA's financial favour.
