I currently have 2 USair MC and 1 LH card (opened in June 2014). Decided to pull a trigger for second LH card, didn't get an instant approval, online status shows "declined". I wonder if it worth to speak with CSR or not - Barclays is very sensitive to other apps (which I have a lot), but in other hand I spend 2x$25K on each USair MC card, so they should be pleased in some way.
Barclays is not as easy to deal with at Recon as Chase and Citi, and it definitely doesn't work to call over and over. But I don't see the harm in calling at least once. But since you already have one open, I doubt you will get approved for another one. I tried the "I need one for personal, and one for business" approach for a second US card, and got nowhere.
