MLW20 posted recently on the AA forum that American Airlines has a a customer service account (@AmericanAir) & AAdvantage (@AAdvantage)account on Twitter, as well as that both accounts seem to be quick with answering questions sent to them. I know UA had a twitter feed that was primarily for spreading fare sales & corp info/press release type stuff. Is this UA twitter account one that I would use for customer service issues? BTW, what is the UA twitter account? Also does CO have a twitter feed that can be used for customer service issues? If so, please share what it is. THANKS.
