Just to clarify: We have no idea if Barclay intended for this link to be available to anyone beyond test marketing perhaps. If you look at the reddit post that announced it, it was generated by someone randomly trying different combinations of 4 digit campaignID numbers and 1 (?) digit cell numbers. But that's a very long search to find every possible link of that form. (It's way longer than trying awayN and travelN and milesN and flyN -- where N was a single digit -- at citi.com for Citi AA card links.)

What we really need to do is find out the format that Barclay uses for links in print ads (such as American Way / Celebrated Living magazines onboard). Do they really use 4-digit campaign ID numbers plus cell numbers? Or do they use something easier to remember (a la Citi)?

Citi originated that pattern of using travelN and milesN and flyN and awayN for the purpose of using them in print ads, including back when they Cit was the ones putting print ads in magazines onboard AA planes. But now Barclay is the one doing those onboard print ads (and maybe some display ads in airports too?).
