I would only fly Norwegian now over Virgin who we used to use.
Slightly less leg room but the Dreamliner are brand new. Took our own food on to save money and it also forced us to take less clothing with us to Orlando because they charge per case.
It may have been me but I did suffer with jet lag for the first time ever flying with that. I've heard it's because they fly higher (he seems why they are cheaper) but you are likely to suffer the jet lag.
At half the price of Virgin, I think they are an amazing Airline and if anything, it means I may be able to get out to Florida more often now as I've always found it to be the cost of flights that are the killer
