Earnings are all over the place on this promo. From a quick scan economy sale miles are -
Domestic/European - 25%
Moscow - 50%
Eastern Europe/Middle East - 50-100% (I have no idea. Of the routes I checked, everything is coded
Sale (E) )
USA - 100%
Now that's what the pop-ups say, and we know that not always accurate !
and as to the domestic economy fares; on the LHR-BHD route, the sale fares are £1, each way, cheaper than 'standard' 50% earning ones.
