Checked Baggage Allowances to Americas - definitions?

[SeatBackForward]

Hi brains trust - and Merry Xmas/NY's to you all. We know baggage allowances to the America's is different than other places, but I have a query about what exactly the wording means . Consider the sentence below, taken from the QF USA website:

The airline whose flight number appears first on your ticket will determine whether its baggage rules or another airline's baggage rules will apply to all the flights in your itinerary

So we know the rules apply to fights to/from the USA. But in the above wording, is the "itinerary" considered to be all flights or broken as the outbound and inbound flights?

For example: SYD>DFW>MIA ticketed as QF/AA flights would obviously get the QF allowance (being the first flight TO the USA), but if the return flight is AA/QF then does the AA allowance count (being the first flight on the return FROM the USA), or is the return considered as part of "All flights in your itinerary" and therefore the QF allowance still applies?

I guess my question is around why they use the word "ticket" as well as "Itinerary"

Because the most significant carrier rule can also apply.

So in your case, the AA sector is domestic, but qantas is operating the transpacific, so the Qantas allowance may apply as the MSC.

But if you were to break your journey, for example a stopover, then different bagged rules might apply for different portions of your itinerary.

At the very end of this page SQ tries to explain the MSC rules… noting they don’t always apply! https://www.singaporeair.com/en_UK/au/travel-info/baggage/checked-baggage/

My understanding is that under American rules, it's not automatically MSC that applies, but whomever is First on the itinerary, they can choose to apply their own rules or defer to normal MSC rules.

But my question is more about, well if the QF baggage applies as the first flight, is this then the same rules for all four flights including the return (ie. the Itinerary) or is just the legs TO the USA that the rules applies to, and then the Return legs FROM the USA have the First Carrier rule re-applied, which in this example would be the AA rules.?

But if you were to break your journey, for example a stopover, then different bagged rules might apply for different portions of your itinerary.

I believe if the ultimate destination is to or from the USA then breaks would still require the America's rule of First carrier applied.

The only situation where it gets complicated is if you're merely transiting through the USA, for example SYD>LAX>LHR as the USA is not your ultimate destination (despite needing to enter the USA doing such)
