Just as a note, Forward Air isn't an air freight only company. They also operate a truck freight line that feeds their air system and leases or feeds into several other carriers. We used some of their trailers in conjunction with a carrier contracted to ABXAir for a while. If you're shipping lowest cost by the pallet-load, it'll be going by truck unless they just happen to need something to fill a flight to where your piece is going. It's really the same as UPS, FedEx, or Airborne, but since they don't have as much invested in public marketing, they can run their fares lower for similar profit margins.
