On a serious note, since American flies to Carib and MX locales where we like to travel for diving and snorkeling, it's going to be a challenge packing gear & clothes in just one carry-on. I will also long for the days I could schlep material aid to Mexico after a hurricane; sadly I'd be less inclined to do so if I have to pay fees for each checked bag.
Here are the exceptions from AA website:
" The following customers will not be charged a service fee to check a bag provided the bag is within the weight allowance:
* For the first checked bag, customers who buy a ticket before June 15, 2008, or who fly before June 15, 2008
* For the second checked bag, customers who purchased a ticket before May 12, 2008
* Customers traveling on an international itinerary to destinations beyond the U.S., the U.S. Virgin Islands, Puerto Rico, or Canada
* Customers who purchase full-fare tickets in Economy Class
* Customers who purchase Business or First Class tickets
* Customers flying on AA codeshare flights not operated by American Airlines, American Eagle or AmericanConnection®
* Customers traveling on government or military fares
* Military passengers on active duty
* AAdvantage Executive Platinum®, AAdvantage Platinum® or AAdvantage Gold® members
* oneworld Alliance Emerald, Sapphire or Ruby members
* Customers flying on the same reservation as an AAdvantage Executive Platinum, AAdvantage Platinum or AAdvantage Gold member or oneworld Alliance Emerald, Sapphire or Ruby member regardless of frequent flier status or fare type (not applicable to group bookings)
* AAnytime® Economy Class AAdvantage award tickets, MileSAAver(SM) or AAnytime First and Business Class AAdvantage award tickets
* First and Business Class upgrades confirmed prior to check in
* AAirpass travel"
It appears that divers going to the Caribbean and Mexico are safe from the new baggage fees, for the moment. Just stay away from the US Virgin Islands and Puerto Rico.
As for taking donations for hurricane victims, try asking the airline for permission for an additional free bag. My sister got one from United to take donations to Africa.
