I've looked through some of the forums, haven't seen this question answered.

What gear does a new guy need? So far I've gotten recommendations from friends on a carryon (recommended 22" to facilitate regional commuting) and an EFB/lunch bag, but I'm sure there's other advice out there.

I also was told that I wouldn't need to buy a headset...

What does a new guy need before training? During training? After training? I'll be in an A320...

Thanks in advance!
