AA Delays To Zurich

Mon May 14, 2001 12:38 pm

why is AA038 DFW-ZRH always delayed.
I have taken the flight once and know a person who takes it about 20 times per year and muct say that it is always late. the average is like about 90min late. why is this?

One probable reason is Zurich itsself. I have never arrived or departed that airport on time. It is running way over its runway and ATC capacities, also at peak times parking positions and gates are hard to get.
Gate capacity will increase when the new "midfield" terminal is opened, but runway capacity won't improve.
But there are other reasons, as well. Aircraft scheduling (by AA), north atlantic ATC restrictions (slots), and so on

Just some ideas

I partially agree with A320FO ZRH is over crowded.

however, I pass ZRH many times a year when I go to Boston and i must say that I always fly on time.
and if there are delays, most of times its not the fault of ZRH. The problem most of the times is that there is a lot of congestion over France. because of this all outbound flights out of ZRH are often delayed. same goes for inbound AC.

and if I think about it ? DFW isn't really a small airport.
it is likely that a lot of the delays start there.

Not likely. AA schedules planes bound for international destinations to arrive more than 2 hours (minimum, 3-4 hours normally) prior to scheduled boarding and there are multiple "spare" aircraft routed to DFW and "held" on the gate until after international flight(s) has departed. DFW ATC places highest priority for departures to international flights needing to make overseas "slot" times. Normally not seen on Pacific flights, but a regular event for trans-Atlantic flights.

I would guess, but do not know, that highest probability for delays is caused by flow control over the trans-Atlantic "Track" system.
