Eastern and National Airlines retired their DC-8 fleet by 1974 including their newer stretch DC-8s,National retired their two DC-8-61s in 1975,yet Delta and United kept their DC-8s til the mid 1980s with their stretch DC-8s leaving their fleet before 1990. Why did Eastern and National retire theirs so early? Did the 1973 fuel crisis have something to do with it?

I'd imagine the huge rises in the oil price, following the 1973 Yom Kippur war had something to do with it.
All of a sudden, that type of aircraft became much more expensive to fuel, adding to the general economic malaise caused in the West.
Certainly. Have a look at National's DC-8 fleet. They had -20, -30, -50 & -61. Basically only the -61s remained after 1973. It was also a way to simplify the fleet around the B727, the DC-10 and the B747 for a while.

Yes, the OPEC embargo in the early 70s resulted in fuel prices roughly tripling, making older 707s and DC-8s uneconomic, apart from the few passenger operators (mainly UA and DL) with signifcant 60-series fleets which were the only DC-8 models certified for the CFM56 conversion program.

Quoting doulasc (Thread starter): Eastern and National Airlines retired their DC-8 fleet by 1974 including their newer stretch DC-8s,National retired their two DC-8-61s in 1975... Why did Eastern and National retire theirs so early?
By the time oil prices spiked in late 1973, only 5 standard/'short' DC-8s (of 16 in their fleet as of mid-1972) remained in service with NA. By that time EA had disposed of all their 'short' DC-8s and retained only 6 of their original 23 'stretch' DC-8-61/-63PFs. It would seem therefore, that NA's and EA's 'early' retirement of their DC-8s was due mainly if not entirely to their being replaced by DC-10s and L-1011s and probably even more so by 727-200 Advanced (longer range, higher payload than earlier versions of the 727-200) deliveries.
EA retired/sold the last of their 'Stretch' Eights (a pair of -63PFs) in February 1974. In EA's case especially, there were other factors favorable to 'early' retirement of their 'long' DC-8s. Before and after oil prices spiked in 1973 (and several years beyond) there was a very strong seller's market for used DC-8-61/-63s. EA's -63PFs were especially desirable (and in very limited supply) inasmuch as they had been designed and built to be converted to freighters at minimal cost and downtime. IIRC EA made a sizeable profit on the sale of their -63PFs. Also, EA had purchased their DC-8-63PFs in anticipation of South Pacific route awards...that went instead to AA (and/or CO?), which made the type essentially redundant to EA's fleet requirements throughout their brief stay at EA.

So, in a way, there are some similarities to the DC-8-60 series and the MD-11, in that passenger operators fairly quickly found better alternatives, but freight carriers really could make some good use of them.

Tango Bravo pretty much summed it up. Just prior to the fuel embargo there was a pretty strong market for the earlier pure-jet models as well. Once the embargo hit the airlines couldn't wait to retire the first generation guzzlers and standardize on the new wide-bodies. AA hung on with the 707's though!

I would also suspect that UA needed at least three engine airplanes to serve Hawaii since ETOPS was not available then. Eastern nor national served routes that required that kind of overwater capability. Just a guess

Quoting airzim (Reply 13): Eastern nor national served routes that required that kind of overwater capability. Just a guess
National's only route at the time of their DC-8 retirement that required 3 / 4 engined equipment was MIA-LHR, which was served initially with leased DC-8-54s, and later with 747s and DC-10-30s. NA subsequently added more routes to Europe, which were served by DC-10-30s, and MIA-SJU, which was served by DC-10-10s and possibly 727s.
Eastern, however, needed 3 / 4 engine equipment for many of their flights to the Caribbean. However, as others have said, EA's large fleets of 727s and L-1011s could easily cover these routes.
These four DC-8-51's were sold to Braniff International in 1973 and were used in a 150 passenger configuration primarily for charters. Later 2 more DC-8-51's from Delta were added and used in the late '70's domestically to DEN and MIA, among other routes.
After Braniff folded three were scrapped. One was converted to a freighter and used in Central America for a number of years. The two DL aircraft were returned to the leaser. The DC-8-62's soldiered on until 1982 when Braniff ceased operations. One was later converted to a DC-8-72 and was used by NASA--this aircraft may still be in use. The others were transferred to several different carriers including Rich International. Some were converted to freighters and may still be plowing around somewhere. One was sold to a Latin American airline and crashed.

Quoting BoeingGuy (Reply 19): I believe that DL applied for LAX-MIA but wasn't granted it during the regulated era.
There was to be a Northeast/Northwest merger and everything was going along well, until the CAB said that the LAX-MIA route, which was NE's, was not going to be part of the merger. NW said it should be all or nothing and they backed out and DL jumped in, but they were also refused permission to operate the route.
Quoting BoeingGuy (Reply 19): Supposedly they sometimes had to stop in IAH on the westbound leg. There was another thread about this NE route a few months ago.
I would think that there would have to be certain times of the year when they HAD to make a fuel stop.

Looking at the historic fleets of NA and EA, it appears to me that both were already well into the process of retiring their first generation fuel-thirsty jets prior to the onset of the oil embargo that started in October 1973. As noted above, the DC-8 fleets of both were greatly diminished months before 10/73.
At the same time NA and EA were phasing out their DC-8s in the 1971-73 time period prior to the embargo, they were also taking delivery of then-current generation narrow- and wide-body types on a more or less 1:1 basis:
NA took delivery of 9 DC-10-10s from 11/71 to 12/72, plus 2 DC-10-30s in 06/73, having retired the same total number (11) of DC-8s prior to the embargo. Two more DC-10-10s were added in 6/75, arriving the month after the departure of their two DC-8-61s.
From 09/72 to 06/73, EA added 15 727-225Adv to their fleet; by 09/73 21 L-1011s had also been delivered. Prior to the embargo, 31 DC-8s had been retired, with only 7 remaining.
Following a similar pattern, from 01/73 to 11/73 Delta took delivery of 16 727-232Adv, 5 DC-10-10s (lsf UA), and 4 L-1011s. By 01/74 16 CV-880s (incl. one written off in 12/72) plus 4 non-fan DC-8-32s were gone.
My own interpretation of the above is that all 3 airlines seemed to have a plan to replace their 1st-Gen guzzlers that had been in progress well before the 1973-74 oil embargo. The concurrent timing of the embargo and replacment of 1st-Gen types with (then) current-Gen types was therefore largely a coincidence IMHO...although, admittedly, I also do not doubt that the fallout from the embargo caused the U.S. airlines to retire a fair-to-large number 1st-Gen 4-engine types before the timeframe originally planned.

Additional comments re: EAL DC8s...
I arrived on the EAL Powerplant Engineering scene in the spring of 1970.
The DC8 fleet had consisted of 14 ea. JT4A-11 powered D821 frames, three ea. JT3D-3B powered D851s (of two different types), 17 ea. JT3D-3B powered D861s and six ea. JT3D-7 powered D863s.
Prior to 1970 several of the D861s were leased to JAL for inter Japan routes configured in high density configurations. Many of the D861s eventually ended up at JAL. Note that EAL had operated the D861s in ~180 to 189 seat configurations (lower in winter due to coats, and higher in summer w/o coats). It is possible to jam in 248-252 seats one class and this was probably what JAL used.
With the arrival of the L1011s (beginning in spring 1972), several of the DC8-63s were kept around to cover for and supplement the at that time unreliable L10s. Every morning on the 10:00AM Maintenance call during the introduction of the L10s, it was reported which of the D863s were covering for the L10s, then one day it was excitedly reported that an L10 had covered for a D863.
But, as soon as the L10s got going, the D863s were gone. By that time I was working upgrading the RB.211-22Cs to RB.211-22Bs and trying to get their early reliability and longevity problems cured.
Comments re: these DC8s as being fuel guzzlers is certainly true when comparing the early '70s to any date after the mid-'70s. IIRC fuel costs were in the $0.11 to $0.30 range. JT3D's had a TFSC bucket low of ~0.505 while either of the new widebody Powerplants - RB.211-22B or CF6-6D - had comparable TSFCs of ~0.35.
Another fuel consumption comparison of the JT3D powered DC8s and B707s is that they used ~2200 gals/hr at economy cruise with 160 to 189 seats while the L10s at a similar cruise use ~2400 gals/hr with ~290 seats. I'm sure that the DC10-10s had fuel consumption similar to the L10s.
It has been about 40 years since I worked on the EAL DC8 powerplants...
You've got to realize some of the facts are a whole lot faded in my memory...
