can anyone help or reassure me with this one

basic details are that i booked flights directly with VA and received tickets by post approx a week later

we then amended the flight return date and since then (may) we have been waiting for our new tickets

i have been chasing them up because it seemed to be taking forever and today i have received a eticket via e.mail that says this is your ticket and pls print off to present at check in

but saying that i have also received an e.mail saying the date change for my flight has been actioned and the tickets are in the post expect them in 8-10days

so i am confused, has anyone had this happen before and do i need to be worried?

thanks Mizzy
