Eeezer have updated their monthly infographic on how airlines are using Twitter (see our updates on this in September and August, and previous months can be found here, here, here and here).

Last month, and thanks to some very negative publicity, Southwest Airlines took the top spot, but they could only secure third place in October, and it’s Delta who once again have taken the crown as Twitter’s most-tweeted airline.

Air Asia sent the most tweets of any airline in October, with Delta, who sent about 700 less messages than in the previous month, beating American for second and third place respectively.

Overall, Twitter is now being used by more airlines than ever, with the total number of tweets sent up by 20% since August.
