WOW AIrlines of course became famous for offering the $99 transatlantic flight. Monitor their prices and they can sometimes offer very good value to North America, via Iceland. Very much in the budget airline style, however. If you like your trips to the US/Canada at budget prices/standards, the good news is they have expanded and from "summer 2016" will be adding LA and San Francisco to the list of North American destinations, currently made up of Boston, Washington DC, Toronto and Montreal. https://wowair.us/magazine/blog/wow...in-2016?_ga=1.105474243.1947405096.1445245397
