To be fair - you have said you like the SWUs the way they are - many here do not. Would you feel the same about the critizism(abuse it way too strong) hurled at DL if the SWUs did not work for you.
Yes I would. Sure, I would like to have upgrades on cheaper fares, but I know that DL must make choices in order to remain an ongoing concern. For every additional benefit, something else would have to go.
The abuse (and I would term it abuse) is not only uncalled for and unseemly, but I feel it trivializes the very FTers that the posters purport to be "fighting" for.
