How much should I tip a Red Cap to help get my bags to the check-in?
At least 1-2$/bag. They work for tips

Suggest you refer the pax to http://www.aa.com/content/urls/curbs...title=curbside where it explains curbside checkin.

Also, I think they are called Sky Caps .. not Red Caps (that may be a UAL phrase). They work for tips . YES.. but some airports have a $2 per bag fee that is described in the above aa.com reference. This needs to be DRILLED into people . $2 per bag PLUS a tip (and locations are subject to change!).

What if my bags are overweight?
Pay and don't block the check-in line kvetching.

For more accuracy (and no ethnic slurs) suggest pax go to this location http://www.aa.com/content/travelInfo...horEvent=false where AA updates the details constantly. It has the fees and details you have not provided.


I flew on multiple carriers? Who should I go see about missing luggage?
The airline that carried you on your last segment.

You must REPORT the missing (or damaged bag) to the last carrier per http://www.aa.com/content/travelInfo...horEvent=false (assuming AA was the final carrier). However, in many cases AA will contact the originating carrier (and all interum carriers) for you.. and will probably blame the first carrier for messing it up. It is AA who should resolve it . but chances are if the bag is declared 'lost' the original carrier will be the responsible carrier.

I know the WIKI is a work in progress and I can edit it .. but one less registration makes my life more simple! And as en EXP who is on planes toooo much .. I need to simplify my life.
