This might qualify as DYKWATI (do you know which airline this is?)

Flying 958 from ORD to LHR earlier this week. The glassware seemed a little odd to me and then I noticed - rather than serving F and J passengers using United-branded barware, the new Polaris service on this flight featured drinks by American Airlines! Seems like the ORD provisioning vendor got a little confused.

Don't know if anyone else has seen this or if it's a common issue. Not a big deal, of course, but clearly not ideal for an airline who has made a huge effort branding its new premium product.
