USAirways sent an email to people who bought the $300-$500 tickets to Israel that I posted about in late August from NYC and from other cities. The email says that USAirways will not be awarding any miles for any part of the ticket unless all segments are flown. In other words if you are booked from NYC-Philadelphia-Tel Aviv-Philadelphia-Toronto and you wind up skipping the Philadelphia-Toronto segment they are saying that they will not award miles for your entire trip.
They’re also offering a full refund if you’re not happy with that. You can email firstname.lastname@example.org to request a refund until 10/15. (And boy are they hoping you will :D)
Of course you can always continue onto Toronto and take a 4,500 Avios flight back to NYC or Chicago for example. Though one-way flights going to Toronto have just $2.50 in tax there is $50 in tax for one-way flights leaving from Toronto. The Chase British Airways card gives 50K signup Avios (Over 11 free short-haul flights) with the fee waived for the first year.
The far more interesting question will be if they can or will stop people from crediting the flown flights to a partner airline like Aegean or United…if you try that be sure to let us know how it goes.
