WOW air (WW, Reykjavik Keflavik) has postponed the launch of its maiden transatlantic route from Reykjavik Keflavik to Boston until summer 2015. In a statement issued via social media, the Icelandic carrier said it had not been awarded the slots it had asked for. Boston would have been its first US destination allowing it to tie the North American market into its extensive European network.
