707 v DC-8
« on: March 20, 2012, 02:03:57 AM »
Well, several months too late I'm coming to the conclusion that I should probably be ordering some jets for my west coast US airline.

Both have similar availability dates.

The current DC-8 (-10) is  slightly heavier and more expensive while holding less people. Its range is too short for transcons in factory config, but I assume with some biz seats we could make it from sea to shining sea.

The 707-120 is then clearly a better plane then the DC-8-10, but only slightly, and there are families to consider. 
Is the DC-8-60 series inter-changeable with older modes (as far as route swapping?)
If I don't ever need any more than 2300 nm of range, how will subsequent models (707-320/720 v DC-8-20 through 55) stack up?

Pretty much all the later variants you ask about are distinguished by increasing range.
The 707-320 and later all have 180 seats and ranges well in excess of your 2300 NM requirement.
The DC8-3X, 4X and 5X series all have 156 seats and ranges in excess of 2300 NM.  (the differences between the 3x and 4x series are all about the type of engine and fuel economy).
So the 707-320 and variants do outperform the early DC 8s.  The 8-55 has a default seating of 144Y and 15C which compares better with the 707.
Lastly, the DC8-6 series is compatible with all the others (both in terms of commonality and turn around etc), and have far greater range or 201 seats (in 3 classes) -- far superior to the 707.  The downside on the 6 series is that you'll be waiting for them for a long time. If you can wait, or want to upgrade your earlier 8s for the later versions, then it is the best.

For as long as I can remember being on AWS and playing JA games, I was told to get rid of 707s and use DC8s instead because they make a HUGE difference when the fuel prices soar!

But that isn't for a while  ;D

Well... to consider are:

707 needs one more pilot (which means in you personnel office you have 3 more pilots per each plane scheduled)
707 yet needs LESS fuel while having (in a 132|10|0 seating) a range of 2800NM which is >600NM more than I get in my 126|10|0 config on the DC-81.

DC-8 is not as good as 707 until the -53 and the -62/3 come out. The prior versions are inferior in terms of fuel usage and range, but still take 1 less pilot (or 3 for the whole week).

Anyways, in previous JAs you could fly profitably a 707-100 till the end of the game, as the fuel prices were gifts.

My biggest consideration when choosing between the two was staff costs and availability (as range was sufficient from both). I thought staff costs would be a much more significant expense than fuel. Plus at the time the 707 was more popular when I ordered.
