Most US based airlines allow seat changes even after check in up to the point where gate agent takes control. Most nonUS airlines do not allow seat changes after checking in. It is most likely system related...
I have got my seat changed at the gate multiple times with various airlines regardless where I am. At EWR I got my seat changed on TAP. At AMS I have had a seat changed on a DL flight as well. Its actually better to change seats at the gate than at check in because once the gate agent takes over most if not all of the pax have checked in and they know what is available.
In Europe, the departure boards are ordered chronologically, while in US, departure boards are ordered alphabetically. I much prefer the US system.
In Europe, planes often times will taxi into the runway and start takeoff roll without stopping. In US I don’t ever remember this happening
Correct me if I am wrong but usually if the plane stops on the threshold then its being ordered to "get into position and hold" because of a landing aircraft or a crossing aircraft or vehicle. Its common at YYZ that aircraft hold on the threshold because of landing aircraft waiting to exit the runway. Many airports such as LHR, CDG, FRA, LAX and I would assume ORD and ATL don't often have landing aircraft on runways they use for takeoff.
What I see in Europe and have seen in Australia is that planes will take off down the runway especially if the load is light or the plane is smaller. I have seen this at LIS, MUC, ADL and MEL. At MEL it was a UA 744 taking off about a 3rd of the way down runway 34. It was only going to SYD and was empty of pax and obviously fuel. I have never seen this in North America no matter how small the plane is.
In the US, remote parking is unheard of for passenger flights. In the rest of the world, it common. I hate getting off the plane via stairs, dash into the bus, ride to the terminal, then find your gate, only to get another bus ride.
I mostly check my bags and never had one damaged; probably half dozen times they didn’t make a connection. I travel with a small carry-on with two days, always worked after I learned my lesson the hard way.
Yes. Busses suck. Although sometimes there is an advantage as bus drops you off at the right connection point and avoids a long walk. But still. Busses suck.
While at YYZ you won't stop at a stand. If you are flying on WG (I am on Dec 7th) you might be bussed to the infield terminal which has its own gates. The benefit to this is that often you get dropped off right outside the baggage claim or the customs hall so much less walking.
