Southwest Airlines» latest schedule announcement says the carrier will begin service August 7 on several new California
routes, including
daily non-stops from Los Angeles International to Pittsburgh; from Burbank and Ontario to Portland; from San Diego to Milwaukee; and from Sacramento to Baltimore / Washington International.
So if you booked economy class and wanted to upgrade to business class (even though you booked a paid fare), the difference in Avios points would be 2X — X = X. For a
route like Seattle to London, with two
daily non-stops, that was only 25,000 Avios each way.
