Anyway, it definitely makes sense for AWA to have hot meals. Given that AWA is trying to sell more FC seats, the food in first needs to be a clear step above what's for sale in coach.
Since they're still in the process of rolling out Buy on Board (a process that will continue until the summer), which requires the FAs to learn new things, I'd guess it'll be a couple months at least.
