Unless it is a high stress business trip where I have no time to waste or I have to return the goodies to my company, I would consider myself lucky - $400 and 4 certificates! These certificates are very valuable.
I agree. To me this is like getting off an oversold flight - except of course most of the time in those situations it is VDB and no one is forcing you to give up a seat. (I have never experienced nor even seen IDB; though I know it happens). Still, an inconvenience but some goodies to play with later.
However they do it IF it is not a special event. Also, the Plat might have to pay full rack rate.
Yes, very likely have to pay full rack rate if they are booked solid and you get in via the 48 hr guarantee.
