This compares what is for sale THIS WEEK for the stated period versus what was for sale LAST WEEK...It does NOT compare to last year or now.
How to read:
ABE-MDT 3>2 APR means a reduction in one roundtrip from 3 to 2 for April only
ABE-MDT 3.8>2.7 APR-JUN This is the raw format of the data which sometimes I'm too lazy to retype. It means that over a month they were averaging a little less than 4 trips per day and now it's a little less than 3 per day. So, basically they cancelled 8 flights per week or so. Airlines are doing A LOT of non-daily ops now, so these fractions are pervasive.
ABE-MDT 4>6 MAY- means an increase from 4 to 6 roundtrips starting in May and continuing
ABE-MDT 4>6 MAY-JUN, 5>6 JUL means the change is only for the stated period May to June and then a different change for July in the same route
Please take it easy on any typos, there was a lot to type...
DFW-CYS 0>2 JUL-
MIA-EGE-DEN-MIA 0>1/WK JUN-AUG, one-way
757 Eqp; I'm guessing this is because of a weight restriction ON EGE-MIA; DEN-MIA now 8/WEEK
ORD-PNS 0>2/WK JUN-
ATL-MEX 1>0 JUN- (Apparently they were just kidding)

While I appreciate your work, one flaw with these threads is they fail to account for capacity increases/decreases. On most of the routes Delta cut frequency, it increased capacity. For example, DTW-FLL went from 5x daily (1x319, 4x320) to 4xdaily 757 -- about a 5% increase in capacity.
I suppose it should be noted that originally this service was scheduled to be cancelled for the summer, so while yes it is showing it going down from 2 flights currently to 1 flight (which is news to me), this service was always planned on being winter seasonal and cancelled in the summer. However QX did announce recently that SUN is going to be served year-round now, with 1 flight to SEA and 1 flight to LAX in the summer. So according to OAG they're also going to keep 1 daily to SUN?

Quoting ERJ170 (Reply 8): So are there more schedule modifications to be made or is there a 320 flight that will be announced soon...
The answer is:
Quoting compensateme (Reply 9): DL's schedule has not been finalized; we'll continue to see adjustments/corrections as DL uploads its schedule updates...
I've been tracking some fairly substantial conflicts (in the June schedules) at SAN for well over a month now and they are yet to be any clearer than they were in February! (They're much different, but no clearer...) Involved are equipment-type turns and frequency mis-matches; other than that, it all makes perfect sense! And btw, I, like you, am hoping for some new-flight announcements to balance everything out.
My advice: wait until about 2 weeks before the effective date and then there's maybe a 90% chance that "what you see is what you get!"

That's easy to say, but do you have any idea how many markets have changes in capacity every week? This week, which was a slow week, it'st 1,389 routes with capacity changes and many of them had changes in several different months, so now you are talking about 4,000-5,000. When DL or UA has a major schedule change it could be 40,000.
Tell me how you would do it, get everybody to agree, and then I'll see if it possible to present that way. How's that? Presenting a problem without a solution is lame. BTW, if you simply say include the seat change, then what if the frequency stays the same, but the capacity craters? Not much of a solution. Also, keep in mind (as in the example below) airlines don't have real aircraft types scheduled in these future schedules so there's always going to be capacity changes as the schedule moves from future to intermediate to current.
My answer is that typical customers care more about departures than seats anyway (because you select your flight by flight time).
Whoever does scheduling at AM must have gone off their medication again. In terms of schedule stability, they are the worst airline on the planet. They make airlines in countries at war seem professional.
Quoting ERJ170 (Reply 8): It arrives in RDU at basically 6:00am. The only 320 departing RDU at all is a DTW flight departing at 6:00am. Where is this aircraft gonna go?
The way a lot of airlines do future schedules is that for mission critical routes they put the correct aircraft in their future schedules, but often they just list everything else as a single aircraft in a particular size category. For example, a 737-700 may be a stand-in at CO for all the 737s or the A320 may be used for all 100-seaters at DL.

I merely pointed out a flaw in your model; on many routes, DL infused larger aircraft & subsequently eliminated frequencies. Thus, per your presentation, it appears DL's cutting capacity while it's actually maintaining or slightly increasing it. I provided this information to educate your readers; in past editions, many responses indicate the writer assumed/concluded the airline added/removed capacity when it fact it may have done just the opposite.
And while I agree that many customers care more about departures than seats (to an extent--many top-elites are demanding/seeking flights with premium cabins these days), your threads aren't catering to customers.

There is no "flaw" in his model--in fact, it's not a model at all. It's a presentation of data.
The "model" comes in its interpretation, which should responsibly be used with other information, to draw conclusions. If DL switched from a 744 to 2 D95's on a route, well...they added a frequency, didn't they? This is just a data point.
Along with 99.9999% of others, I appreciate Enilria's work. For many markets/carriers he lists that are of interest to me, aircraft seating capacity doesn't change much--but frequencies change often. Thus it's a nice off-hand reference.
The moral of this story is to be smart and make sure you rely on facts from all sources available to you to make rational conclusions. Don't rely on others to bring things to you on a silver platter, and don't assume they should. That's a nice life lesson as well.
But in all honesty methinks you're putting your fingers in others' pies just to stir up trouble.
Unfortunately, I do not think that is possible since the Steelers A319 is a US east aircraft, and US east aircraft do not transfer and connect to old HP (west) spokes through PHX or LAS. I could be wrong though.
Anyone likely to pick this up. If wiki is right DL are the only airline serving this route. Didn't Spirit once fly it? Would they reconsider it again? Or JetBlue or AA? I would suggest US but if the slot swap goes through then there is little chance they would be interested

I agree. AM is completely lost. I just wonder if this is an error or something. I mean, the flight has not even started yet! Maybe a Deltoid with some knowledge of ATL or of the DL-AM ops can shed some light?
