The discourteous and crass response that is slowly turning DDF into a cesspool of hostility.
That's the way
you understood it.
The guy asked how he can be
sure that they will check his bag through and my response was that there is no way to ensure that. He bought the trip as 2 separate tickets in order to save miles and the trade-off is that he may have to recheck his bag. BTW I have done the same thing in the past and had to recheck and even tough it was annoying, I accepted it as the cost of saving those miles.
I hope that in chaim0m's case things work out and he will be spared the annoyance and enjoy a safe and pleasant flight.
