Used this service twice to transport a soccer team. It's not cheap but it's top notch service with a very personal touch. You can also access some airports that DL doesn't service which is a nice bonus.
This service is good but it's a terrible option and waste of money if you're looking to grab SM's or impress someone. If you need to transport important people to important places, then this is a viable option.
If you call the help desk ask for Janice D, pure sweatheart and will go above and beyond to make sure your needs are taken care of. If you're flexable with your travel check the link below and you can deadhead your way across the country. The second time I used this service I was on the end of some of positive shi- luck and arranged a r/t through dead legs.
