Flying MD-90 And MD-80 On Consecutive Days

Alright guys.. here goes: on March 5th, I'm flying a DL MD-90 from SLC to SEA. Then the next day, I'm turning around and flying an AA MD-80 (Super 80) from SEA to ORD on my way to LHR.

I thought that since I'm flying the 2 aircraft on consecutive days, it would give me a chance to compare the 2 and find their differences. What should I be looking for? What external differences? Internal (Cabin) differences?

Once I get back from the UK in March, I'll be sure to give you a trip report. It should be an interesting one as it involves FOUR airlines and at least that many aircraft types!  Big thumbs up

(DL MD-90: SLC-SEA, AA MD-80: SEA-ORD, AA 777-200: ORD-LHR, RyanAir 737: STN-SXF, EasyJet 737: LGW-Belfast.)

(Note: assume the same airlines and aircraft types in reverse for the return, except for the return on DL SEA-SLC, which will be a 738.)

"What should I be looking for?"

Uh... one is longer than the other.

LOL.. thx for pointing out the obvious Fox. Are there any other differences I should watch for?

Yeah... one of them has more seats than the other. I can't remember which.

A strange difference, at least on SK, was that one has a 2-3 config, while the other has a 3-2 config - and, being the newer one of both, the MD90 has more modern (and quieter) engines.

Other than that, I couldn't tell any difference...

The MD-90 have larger engines compared to the MD-80 series.

Internally there is very little difference except what the individual airline(s) chose to install. Externally MD90 differences are: (a) 50% larger engine size, (b) vertical tail extension, (c) two air scoops on fuselage right side [nose gear and wing root] for electrical system cooling. Other than being quieter you probably won't notice much difference.

The MD-90 is five feet longer than the MD-80. The plug is forward of the wing.

Some differences you are likely to notice as a passenger: quieter engines, slightly longer, and newer cabin, with drop-down LCD screens.

I had a similar comparison opportunity a few years ago when I flew FUK-KIX on a JAS MD-90, then back on an MD-81 a couple of days later. The -81 sure seemed old and tired!

Another external difference is that on the MD-90 the overwing exits are separated by two windows, instead of just one on MD-80s. Have a nice trip.

Performance wise, keep in mind that you will be on the MD-90 from and elevation of 4,000+ feet and the MD-80 will be departing near sea level. The 90 will probably do just as well from the higher elevation as the -80 from sea level. Keep that in mind when you think about your takeoff run and initial climb.

The best thing about the DL MD-90 is the IFE - not found on the 80s.

Make note of the leg room difference between the DL MD-90 and the AA MD-80. With AA's MRTC, I expect the leg room to be better. Also, AA has newer seats with adjustable headrests. AA MD-80's are my favorite domestic US aircraft.
