And also, those $800, $1000 are just United voucher. The worst is they only issue 16 or 20 $50 vouchers, you can only use one voucher each time, and can only book through phone (which some people say is usually more expensive than online), oh and expire after a year. When more people know that, they are not stupid, it's useless even if they give you $10k.
Basically they caused this no volunteer situation themselves.
