A few months ago British Airways made some pretty substantial improvements to their online award search tool, whereby they began allowing you to search for multiple classes of service at the same time. While I don’t find the British Airways award search tool to be the most intuitive option for searching OneWorld flights, it does display availability on more OneWorld carriers than any other website.
Anyway, it appears they’ve made yet another improvement to the website, though admittedly it’s more minor than the previous one. Now when you search for award space and select your flight it will quote you the total price in both Avios and dollars on the search page, rather than making you go to the results page. This makes it much easier to compare the cost of various award options.
Next on my wish list for British Airways’ website is that they start displaying Alaska Airlines award space. I book Alaska tickets all the time, and it’s such a pain to always have to call to book. Furthermore, for Executive Club non-elite members it sucks to have to pay the phone ticketing fee, given that the flights can’t be booked online. On one hand I also wish they’d display Aer Lingus award space, though at the same time I’m happy they don’t, since it means fewer people are competing for those seats (and flying Aer Lingus transatlantic is the single best use of Avios, in my opinion).
When possible I continue to use American’s website to search for OneWorld award space. It allows you to specify whether you want to search award space for flights with connections or just nonstop flights, and displays award space for an entire month at a time. The big catch is that they don’t display award space for several OneWorld partners, including Cathay Pacific and Japan Airlines.
