It appears as if British Airways has changed their award search tool for the better. The actual page where you input your dates and route remains the same, but when you display the results it gives you a pretty awesome calendar results page.
The old search was pretty awful because it first searched British Airways award space and then partner award space. So for example if you wanted to search award space from Tampa to Miami you’d first have to go to the British Airways results page (which obviously showed no availability since British Airways doesn’t serve the route), and then click on a button to search partner airlines.
Now partner airlines automatically come up. For example, here’s what I get when I search award space in coach from Tampa to Miami:
Then you can easily switch the dates you’re searching, either by clicking the exact date you want on the top tab, or by clicking the “Previous Week” or “Next Week” button.
I actually primarily use the British Airways tool for searching Cathay Pacific and Japan Airlines award space. For searching American, British Airways, and Qantas award space I far prefer American’s website. This change makes it much easier to search space on those airlines, since you’re not first forced to check routings that involve transiting London Heathrow on British Airways.
Now I just wish they’d add the option of booking open jaw/multi-city itineraries online, and also that they’d start allowing Alaska award tickets to be booked online.
