No longer need to codeshare to EIS: AA flies direct MIA to EIS. Are your prices per person or for two people? Here's my thinking: do AA CLT-MIA-EIS, which may include free bags, depending on status and ticket type. Fill the bags with food. Figure out your weight limit going to Anegada and take stuff up to the limit. Even if you don't need the stuff, your friends there will be thrilled.

We now buy business class tickets from Memphis, through Miami to EIS. Four 70-lb bags are included in the ticket. Trust me it's not clothes, but spare props, chain saws, grinders, Bosch bulldogs, etc! If you bring the items with you, you only pay duty on the item, not shipping.
