Simple Question: Baggage Allowance on Upgrade
 

So I'm reading the CO website trying to find out the rules on baggage allowance. For First and BF, it has the following to say (emphasis mine):

3 Checked Bags: Maximum 70 lbs (32 kg) and 62 linear inches (157 cm) (total length + width + height) per piece. Ticket must reflect confirmed seat for segment in which customer is checking in.

I read this to mean that, as long as you have an F or BF seat, regardless of whether it was obtained via purchase or upgrade, that you can check a 3rd piece. Does anyone have any experience that would confirm or refute this thinking?

You are correct, any time you are in FC you get the 3 bag limit and weight restrictions. I actually used an upgrade once as I was moving and would safe enough with the extra bag and it was a longer flight to make the upgrade worth while.

Upgrade to BF gets you the third bag.

Now the question is if you pay to check a third bag and then get upgraded at the gate (ordinary F), do you get your money back? (I assume the answer is no).

No...you wouldn't have been entitled to the third bag because at check-in you were not in F. So the cost would still be in effect. See below:

The rule doesn't list a time. At boarding the ticket does "reflect confirmed seat for segment in which customer is checking in.":)

Thanks for all the info. Looks like it should work for my purposes.

Oh, but I beg to differ. :p

When you "check-in", be it OLCI or at the airport you are confirmed in coach. Whereas if you get upgraded at the gate, technically, that is AFTER you have checked in. :D
