The new bedding is a vast improvement as is the new tableware. The food is not much better than the old Do&Co catering on this route but then again LHR-JFK is BA's flagship service and has always received an extra level of care and attention.
If BA can roll both the Do&Co and White Company partnerships successfully, fleetwide, they will go some way to undoing all of the harm that has been done to their reputation after the last three years of cost-cutting. Add in a new seat due in 2019 and then the only issue that remains is the poor quality of the lounges.
BA don't exactly have an easy road ahead of them but for now at least, it appears that things are moving in the right direction.
