Hi,
"I don't see what the point was if they never intended to do anything... "
==> I don't know that it's their intention not to do anything .. We'd have to be "inside" Copa to know that... The processes for lost/delayed/damaged bags DOES require some leg work and back-office processing.. but I do think you have every right to expect a reply-- one way or the other.
"I think at this point the lack of response irks more than the money. "
==> I agree.. I think even if it's a 'no' you deserve to be informed of that.
What I *suspect* will be the end result is that they'll first determine what the actual damage is--- next they'll filter that documented damage thru whatever is listed in their CoC's as excluded items... Whatever remains will then be deemed a valid claim..
Many carriers will also factor in a depreciation schedule/rate to you bag, in part to recognize that notion that it does have a defined life span and as it ages, the value of it drops. A parallel is your car-- it's value drops in line with it's depreciated value, so any claims take this depreciation factor into account.
Not all carriers do this, but many do.. So IF this applies, they'll reduce your settlement by some factor to account for this.
At this point, what I would do, (as noted in #1) is make sure you know what is and is not the rules that pertain to your case.. Be sure you read for any exclusions and the like.. Next gather your supporting documentation (repair receipts, comparable new suitcase prices, etc)
Next, I'd reach out, in print, to Copa's Central Baggage Office (CBO)-- most airlines have one, and most call it just that.
I'd ask them for a status update on your claim (this does assume you've filed the proper paperwork for a claim and done so timely)..
Commonly if the claim is still in the process, investigation or settlement stagest, it will be handled by the CBO staff.. If the matter is closed and just waiting for settlement funds disbursement, that's usually done by their accounts payable department or accounting.
Do remember that most CBO's and other back-office functions aren't 24/7 operations.. So you may have to factor in weekends and holidays when you consider the timeline for awaiting a reply.
Be persistent and keep everything in writing-- be that email or print. These kinds of cases are all about documentation and what does their CoC say. So be sure you know what's applicable in your case and that you have all the necessary documentation to support your claim.
