US Airways joined British Airways in the oneworld alliance on 31st March, and since that date you have been able to redeem your Avios points for flights on US.
In summary, here are their UK and Ireland routes and the tax required. These are for return business class seats:
Dublin to Philadelphia – £28 (says £49 then reprices)
London to Charlotte – £194 (say £215 then reprices)
London to Philadelphia – struggled to find but imagine as above
Manchester to Charlotte – £165 (says £186 then reprices)
Manchester to Philadelphia – £165 (says £186 then reprices)
Edinburgh to Philadelphia – £162 (says £185 then reprices)
Glasgow to Philadelphia – £161 (says £170 then reprices)
US also flies Dublin to Charlotte and Shannon to Philadelphia over the Summer.
As you can see from the list above, ba.com initially shows a slightly higher taxes figure on the page where you select your flights. Once you click through to the payment page, it drops by £10-£20.
This differential has now got FAR more drastic.
When you select a US Airways flight on ba.com, the initial page now adds fuel surcharges. Take a look at this example for Edinburgh to Philadelphia. It used to show £185 but now shows £504:
However, when you click through to the payment page, it reverts to the original ‘no surcharges’ price of £162.
I don’t know what this means. In theory, BA should be adding surcharges to US Airways tickets because it is part of the transatlantic joint venture between AA, BA, Finnair and US. So far it has not done so.
The fact the fuel surcharges now show up on the initial flight selection page is a little worrying though. If you were planning on booking a US Airways redemption I would do it sooner rather than later, just in case. It could save you £500 or more in tax for a couple …..
