ALL YEAR LONG
This depends as London has 5 airports servicing it. Generally speaking, although probably the furthest away, Luton Airport is the cheapest to fly into and Heathrow would be the most expensive.
It varies. Currently it is Qantas.
There is no such cheapest time of the year. You just has to book well in advance for your flights and you get a best deal. Say almost one or two months in advance and try to fly on Saturday you will get chap air deals.
I think... November
January and February are considered out of season and are generally the lowest cost.
If you want to fly cheap book your seats 6 months earlyer
