i qualify for 1k on about 45 domestic round trips a year. I would LOVE to have 12 CR-1s as opposed to 6 SWUs.
To people's point that it would be difficult for IT, I completely disagree. Look at Elite Choice, look at Ski Kits, look at TRAVEL OPTIONS!!!! they are very much able to create on options menue for 1k's.
That being said, I understand why they don't. I won't use my SWUs, therefore they win. But is it really best practice to be "scamming" their top elites (giving them benefits they KNOW they won't use)?
