Anyone know the direct operating costs of the 707-320B? I've heard estimates that fuel consumption was roughly 1200 gallons per hour. Other than that I didn't know how much was put back for insurance, maintenance, crew, etc. I'm talking in today's dollars roughly. Because BETA and SkyMaster down in Brazil have to be paying something and if those things are as thirsty as everyone says, it can't be cheap. Any info will help, thanks!

According to Giant Jetliners by Guy Norris and Mark Wagner, the 707-321B had a DOC of about 0.871 cents per statute mile. I'm not sure whether that's 1960's cents or modern cents, though.

Gee that seems low. That's only approx $390/hr. The last time I did a business plan for operating a 737-200 was in 1990, that was $5,000/hr total costs, of which approximately 35% was fuel. Do the math on that, and figure 2.5 X for a 707 and its around $4100 1990 dollars = $6200 or so today, plus whatever oil cost increases have occurred since 1990.

The 757-200 is about 1050-1100 GPH so the 707 must be much higher. I think the DC8-62 is about 2800 GHP so that may be a much better estimate for a similar vintage 4 holer.

The B707-320B (advanced cowl) aircraft consumes, on average, 1750 USGallons/Hr.

Operating cost therefore would be most dependant on fuel cost.

Insurance is another factor. I'd guess atleast $20k a month.

Anyone who's worked with N88ZL or Omega on the forum that has any info?


I don't know whether JTD -219's or -7's would get the lowest fuel consumption.

Boeing 707 burns about 6500 KG of fuel for first one hour of flight if your departing with maximum T.O weight & as you know fuel consumption decreases as weight decrease, also I would like to note that fuel consumption of the 707 is equal to the airbus 300.
I would like also to note that the 707 can take up to 40 tons of payload that is equal to the Airbus 300.
About spare parts they are the cheapest in the market & so simple to find.
I also want to mention that the Boeing 707 is a money making plane till now for cargo airlines.
I'm sure Beta Air is pleased with their Boeing 707 operating costs .


Regards.
