Helluva broad topic to ask as a first question. They'll cope. The number of good productive people outnumbers the media types and half wits.

Getting rid of the lazy militant pampered ground staff who think they're better than they are.
Outsourcing everything but the pilots, cabin crew and engineers because let's face it, the rest is what handling agents are for.
A summer without a strike.
Getting shot of anyone who thinks it's still 1979 and the state airline owes them a living.
Focusing on a single terminal operation that works smoothly.
Realising that done properly ( see above ) BA Gatwick can compliment Heathrow.
Deciding to replace all those B737s with shiny new A319 / A320s
Getting BA Cityflyer to make money
Realising that with a third runway it may be worth looking again at maintaining UK regional services and possibly re-linking ( again ) to Jersey, Inverness, Belfast etc.
