My candidate is AA 1562, JFK-PHX, scheduled daily at 09.59 AM:

This is usually a LAA 737 which lands at LGA the night before and goes to the hangar. It is then ferried empty from LGA to JFK in the morning.

The scheduled departure from LGA is 08.00 AM, landing in JFK at 08.40. The morning traffic at LGA between the hours of 7.00 and 9.00 is among the worst in the day, with take off waits over 30 mnts and this has been the case for years.

The plane is overnighting at LGA. There is therefore no problem of incoming flight. One would hope that some high powered brain in the system would think of scheduling the LGA-JFK flight at 07.30 to insure a timely departure from JFK... but no. The same machine usually goes on from Phoenix to Sacramento, unless another plane can be substituted for the late arrival in PHX. From then on, the delays snowball.

Who can believe that the cost of reaccomodating passengers with missed connections ( and this is an almost daily affair...) is less than paying an extra 30 mnts to the crew ferrying the 737 from LGA to JFK ?

AA 83 too AKL delayed 2h10m last night. What's amazing is it left at 0030 and AA83 from JFK landed at 0031 and was going to be at the next gate.

Cannot even imagine landing 3h late just to see my connecting direct flight pushing back as we push in.

AA98 (ORD-LHR) again 2 hour delay last night - wow; the 34% on time is deserved for this one - maint again - this time didn't sub to a three class 772

Not sure where you are getting this from. It happened once in the last week.
Most other days flight 1562 left on time and the plane used came inbound as flight 261 from SEA landing around 0630.

Agreed. AA is NOT routinely scheduling a ferry flight from LGA to JFK to bring a 738 for the JFK-PHX flight. It may have happened once, and was probably due to storms/weather causing planes to be out of position (that or a maintenance one-off).

Last JFK-SEA flight of the day (AA267) has been brutal lately. Had taken it several times lately and had delays so had arranged to take my family home on ISP-PHL-SEA routing yesterday, which was thwarted when inbound aircraft for ISP-PHL was super delayed. Called EXP line and asked to be moved to JFK-SEA to avoid misconnect and all 5 of us were moved (3 right into F no less). Got the other 2 up into F at check in. Invound delay + minor mechanicals meant we didnt push until nearly 10pm. Then long taxi and wait on the runway. A look at the recent performance shows a 1am or later arrival in SEA not uncommon. Ouch.

Already delayed for tonight (6 hours in advance).

As others have pointed out-- who told you this?

To the best of my knowledge and unless things are so disorganised that they change on a daily basis, 261 from SEA turns around in JFK and departs about an hour later to Las Vegas.

This by the way probably explains why the JFK to / from SEA and LAS 737s are often part of the sub-fleet with new interiors and good in-seat IFE, whether Phoenix rarely has them

What costs are those? It's not as if they actually add resources or spend money without a protracted battle (unless you have an AAngel on your side.) And that battle usually doesn't resolve until after the trip has been taken.

Almost every flight I am on seems chronically delayed this year

me too.....have had THE WORST luck this year and am starting to give up.

Same, but especially on AA and B6 for whatever reason. Though I've had an unsavory amount of travel to, from, or through the NY airports this year, so I'm tempted to blame the B6 issues on JFK/NY more than B6. Interesting though that 100% of my intercontinental flights from JFK have been on time (and all have been operated by foreign airlines).

AA has been late all over the map for me this year though, JFK, LGA, LAX, DFW, MIA, MCO, PHX, you name it. The worst offending aircraft for me this year have been A321s by far, followed by 777s. Oddly, all of my 757 and 767 flights have been on time.

MIA based for me and its usually 777s that go mechanical. Very little issue with the 738, 321, 763 and 319. Maybe I'm lucky. I usually take morning flights so I have few departing issues but getting to a gate a night is a real venture. Thank god I am not connecting to South America.

Currently delayed 4h50m, 35m was for late arrival of aa2225 and the rest is because of the computers failing.

No announcements from 1245 until 226, just auto delay updates 10m at a time.

Absolutely terribly handled so far by AA, lounge staff is great staying open and even bringing up sandwiches one they were finally brought to the gate by AA nearly 4 hours into the delay.

This is absolutely my last paid revenue flights on AA.
