AC 446 delayed today because of... overfueling?! How can that happen?

AC 446 today is at least 1 hour 20 minutes delayed because the plane was “overfueled”....

This feels like something that can’t happen. Anybody ever heard of this before?

I've seen them offload excess fuel due to performance (usually temperature and load) issues, but from YYZ to YOW? Seems like a pretty short flight.

Maybe there was some form of spillage.

Last night flights from YYZ to YOW were delayed by "shortage of ATC at YYZ " according to the gate agent. My departure scheduled for 9:30 PM departed at 12:20 AM .

Interestingly lots of GTE boarding passes but plenty of seats

I've had it happen on planes up to a 737 in size.

Last minute equipment swap on the route, overfueled because on a short trip the extra fuel would put the plane over the maximum landing weight (either for the runway or for the mfr's rated landing weight).

Be glad your fuelers took out enough, but not too much. Air Canada has famously landed with zero fuel and zero engines before. My backpack Gimli Glider tag doesn't even smell like Jet-A.

The shorter the flight, the fussier the maximum landing weight and minimum buffer amount can be. There are times on tiny hops like GRR-ORD where 10-15 minutes on the ground for an extra round of deicing and anti-icing can mean a return for more fuel since the margin between not landing overwieght in Chicago and having enough to divert to Milwaukee can be very very small on some aircraft types.

For those who have not memorized the schedule, this is a flight from YYZ-YOW. Those sorts of microhops are prone to overfueling when a combination of wind shift and temperature occurs. If the aircraft was fueled for a departure to the SW and a landing to the South, but wind shifts cause that to be straight out and in, that would shorten the flight sufficiently to require fuel to be removed so that the aircraft does not arrive over YOW too heavy to land. That would result in you flying a holding pattern until enough fuel is burned to land.

This has happened to me, on WS, flying YQM to YYZ.

It was a total gong show which in the end meant an overnight at the Delta Quebec City on WS’ dime.

I have learned something new today from your post and others upthread - thanks!

But I thought memorizing the AC flight schedule was part of the test we all took when joining this forum.

How many times have they renumbered flights since then?

What? You didn't take the refresher course?

@ensco too bad I didn’t see this earlier, was also on this flight..... we could have had an impromptu mini do in the lounge.



Ended up calling the concierge and got put on AC 448 and avoided the delay

Maybe the fuelling team/driver was the same ones from 8615

I believe they are going to require re-training on the FT simulator before you can get back online.

On March 28, 2018, I flew on a Boeing 787-9 on American Airlines flight 281 from DFW to ICN. It was delayed more than an hour at the gate, because it had to "defuel." I found it puzzling that it would have taken so long, given that on a westbound flight to Korea it would have needed substantially most of its fuel capacity in the first instance.

The YOW / YYZ flight numbers have been the same for quite a while now... not only do I know where that flight number is going, I know at about what time of day it is as well
