Why would American airlines load hundreds of passengers on their flight # 622 to Miami WITHOUT having a pilot?!?!? Now we are stuck sitting on a plane without any idea of when we are taking off!! Not to mention, they took our luggage at the gate, stating there was no more overhead space, which was not true !! Plenty of overhead space! But most of all , we may very well miss our flight from Miami to Barcelona! I do want to thank the flight attendant who helped me lodge this complaint. On the other hand, we're still sitting here with no PILOT!!
