Had a recent flight from Raleigh,NC to Providence,RI to attend a wedding. Connecting flight out of Charlotte. Got stranded in Charlotte—-flight was cancelled after more than 2.5 hour delay because there was NO PILOT! Lost the expense of the hotel I paid for in RI—-had to pay out of pocket for hotel in Charlotte because the voucher we received for contracted hotel did not work—-the hotel never answered the phone! Missed pre wedding party and attended actual event on 4 hours sleep. Rude gate attendants in Charlotte—-inadequate staffing to get a voucher(more than a city block long )and only one person working the customer assistance line. Had 6 flights with AA during a 48 hour period and only 1 flight on time. Emailed the CEO of AA,Robert Isom—-no compensation to be provided for lost hotel expense; will provide reimbursement of amount they have for voucher even though my cost 275.00. Mr Isom supposed to be turning AA around—-my experience indicates it has not happened. If you don’t want to arrive at your destination on time;want to lose $$ on hotels;hang around for hours in airports waiting to go standby and then not—-please fly AA. If you want to be treated respectfully by everyone from CEO to gate agent—-fly any other airline.
