I've flown to Iceland 7 times in the last 4 years from London and have always used one of the following airlines
Iceland Air is the better carrier - more legroom, en flight entertainment, luggage included etc. Whereas Wow is the budget option and you have to pay for everything (booking, paying by credit card, luggage) and there is less leg room and no entertainment.
For combining flights I've always found expedia to be very good.
One thing worth bearing in mine with Iceland is the international airport is in Keflavik which is about an hours drive away from the capital itself. There is an airport in the city itself but its only used for domestic flights.
