You are not a lawyer and evidently have no legal training. (I do not know what "a luggage issue" is, but there is an issue of improper and negligent bailment to a third party and failure to exercise duty of care in a bailment.) There is a license to practice in front of the US Supreme Court the wall of the house I maintain six blocks from to the Federal Court in Milwaukee (due to the conveniently short walking distance). I will not have any uphill battle (many complications aside, corporations with a business presence in the US are prima faciesubject to US primary jurisdiction), my barriers to entry are low, and I consider this a bit of sport (can AF be stupid enough to let it go to me seizing the lounge at O'Hare //1 -- other companies have managed worse by ignoring relatively small judgments). And with all respect, "just my opinion" seems to frequently accompany opinions of low value.

//1: yes I know-- probably not their property-- better to try impounding a 787 if you have an outstanding judgment that has been ignored--
