We found round-trips to New York for as little at £275 with new Scandi low-cost carrier Norse. The catch? You can’t bring more than a T-Shirt or two. This is Norse’s economy light fare, which only includes a small under the seat bag. Likewise, JetBlue could fly you to the Big Apple and back for just under £450, again with just an under the seat bag.
Our snapshot research reveals that the key to squeezing the value for money out of no-frills carriers is flying off-peak and packing light. While Norse was cheaper than British Airways and Virgin Atlantic by nearly £100 for flights in October, even with a proper cabin bag included, when we compared flights to New York for August, the cheapest ticket was actually with British Airways (which includes a 10kg cabin bag in its economy basic fare). Go with Norse and you’d pay £192 more for this same trip after adding a 10kg cabin bag for £49 each way. If you want to eat a meal during the eight-hour flight, that’s another £24 each way with Norse whereas this is included with BA.

Norse did come out cheapest for our trips to Washington DC and Orlando in August, but only beating BA by £11 on the Orlando flight. Norse’s economy classic fare, which includes a 23kg checked bag, 10kg cabin bag and a meal, came out at £893. The same flight with BA’s economy standard fare, again with a 23kg checked bag, 10kg cabin bag and a meal included, was £904 and for that you get free standard seat selection at check-in too (Norse wanted to charge us well over £11 per seat for this).

When it came to our flights to DC, there was no denying which airline was cheapest. Norse could fly you there and back in August with 23kg of hold luggage, a 10kg cabin bag and a meal included with a £781 economy classic ticket. That’s £50 less than the next cheapest fare from PLAY (828) and a whopping £370 less than Virgin Atlantic (£1,150), the most expensive in our comparison.
