Did anyone (Randy or Milespy founders) attempt to contact Radisson about this issue?

I think that Radisson may be losing money on this deal, and if so doesn't it follow that they might be willing to let individual customers take advantage of this deal but may be hesitant to allow massive arbitrage by a commercial entity.

I'm also afraid that this makes it less likely of similar future offers. And it makes it more likely that Radisson may put caps in their program about how many miles can be transferred to airlines in a year. Latin Pass imposed such a cap on transfers to Marriott Rewards.
