British Airways offers three times a week service between Las Vegas and London’s Gatwick airport (they offer daily service to Heathrow).

The Gatwick route must not be doing well, because are offering a 15% discount on the points required to book this Vegas-Gatwick flight.

The 15% discount is for bookings made by February 28th and travel through March 31st. All cabins are included in this offer though the flight does not have a first class. And because of high fuel surcharges I don’t find Avios redemption for economy to be worthwhile. Business class is where I would focus. This can be booked online or by phone (though phone bookings incur a fee).

The discount applies to awards and not to upgrades. You can discount the mileage cost of a miles and money award, but the discount doesn’t reduce the cash portion of that award. And the discount doesn’t reduce taxes and fuel surcharges.

A business class award is normally 50,000 points each way, so a roundtrip award under this offer would cost 85,000 points plus taxes and fuel surcharges.

Fuel surcharges run $904 for a roundtrip business class award, and you pay the UK’s “Air Passengers Duty” often referred to as the ‘premium cabin departure tax’ which will run $204. All in taxes look to be about $1184.50.

Still, British Airways has at least 2 business class award seats available on most dates during the promotion period. Which shows how lightly booked the flight is, consistent also with why they’re offering to discount these awards.
