Free Flight to USA "Thats if if you Like Drin

Just been to Sainsburys and their is a promotion on offering a Box of 6 wines "Turning Leaf" for 36.99.However the company{not sainsburys} is offering a Free Flight to the USA {Excluding Taxes & insurance} to about 5 airports, although for an extra 60pound they say they can take you anywhereels in the US.The only catch i can see is it only 1 flight per household and if their is 2 of you. The 2nd person pays full fare. Would be interested if anybody else is tempted by this offer????? or will it turn of like the hoover fiasco???? Digging out my black book for friends who are in the US
