According to ATI's website, they still offer charters using their DC-8-62 Combis. From their site:
ATI combination passenger/cargo "combi" aircraft are specially designed to accommodate not only important cargo, but also the most valuable payload of all - passengers.
With the only DC8-62 "combi" fleet in the world, ATI has the ability to simultaneously transport 32 passengers and 10 pallet positions of freight on the main deck, but in distinctly separate areas of the aircraft. There is also below-deck capacity for baggage or additional cargo. These aircraft are truly exceptional because they are the only DC8's in the world that are FAA approved to operate in this configuration.
The passenger area has a similar design to that of standard passenger aircraft. Our DC8's are complete with overhead storage, lavatories and galleys capable of serving hot or cold meals with beverages ranging from a light snack to a multi-course meal. The 10 position cargo compartment is in a fully operational standard upper deck configuration, with a ball mat and roller system to enable FAA approved pallets to be loaded through the large upper deck main cargo door.
In addition to having a uniquely functional design, ATI's "combi" aircraft meet U.S. FAA Stage Three/ICAO Chapter Three noise regulations worldwide. The long range full capacity of ATI's DC8 "combi" aircraft allows us to operate over 4,000 miles non-stop, even with a full load of passengers, baggage and cargo.
ATI not only offers the best in convenience and flexibility, but passenger service as well. ATI's friendly and service-oriented flight attendants are dedicated to making your flight the best it can be. ATI offers a low passenger to flight attendant ratio, in-flight movie options, hot or cold meals and individual, personalized service on every flight.
