Dear JAL fellows,
I just booked two JAL legs for a domestic trip next august and my itinerary will be ITM-OKA-HND on separate tickets.
First of all JAL doesn't ask you to provide an email address so I haven't received any confirmation email but just printed the confirmation page that comes after you give credit card details. I think everything worked fine but I'm wondering why I wasn't given tickets numbers: all I have is a reservation number. That's correct?

Than I bought both legs a J ticket: why doe it costs just 1.000¥ more? It seems silly to me people buying Y ticket if you can fly J for just a couple of beer more.
I know it is domestic J, but still wondering if there's any hidden "surprise"!

thanks for your help and understanding
cheers maclover

p.s.: I tried to look if these questions were answered in previuos threads but nothing came up
