Id50/id90
Hello Danja,
ID tickets are probably the best benefit that airlines provide for their employees.
For example you can fly from Europe to US and back for less than 100EUR. And ID00 are even better, you can fly for free if there is no tax applicable. I remember when I flew to JFK and back in J/Cl for 15EUR and YUL was even cheaper, 0EUR (free) :-).
And that is why I do not care about any rule in QR because ID and ZED tickets are worth everything. Yes, QR is not my first choice, but I would be extremely happy if I could join them at least.
