Airline flight bags – back in fashion ?

Hi all, I’m new here so firstly want to say hello.

Has anyone noticed a marked increase in the amount of retro airline flight bags around recently ? I certainly know about it as I have a website selling them – http://www.inretro.net . I work with designers whose bags are so good that they are actually approved and licenced by the airlines themselves – KLM & JAL to name but 2. I’m also interested to know if anyone has any obscure original flight bags from the past and for which airlines.
