Discounted fares are available on select dates between 9 January and 27 March, 2013, covering the ski season in Colorado's Rocky Mountains.

Flights are indirect via Reykjavik, but at around 10 hours each way, flying time is quicker than the same route with other airlines. Plus, the baggage allowance includes two pieces per person, at up to 23kg each.

As part of the sale, flights to Boston are also discounted to £413.
