Flight was delayed 10 hours due to 3 mechanical failures. AA only gave out food vouchers if requested. Voucher was $12 about $1.25 per hour - ridiculous this barely covers a bag of pretzels and water. Many elderly passengers were left in discomfort and shuffled from gate to gate with each failed aircraft option. Flight times and gates continually revised so one could not even feel comfortable going to a restaurant for a hot meal and chance missing an update. AA's fleet clearly are not well maintained as evidenced by three plane failures. I would never feel comfortable flying with them in the future. This was an awful experience lacking in customer service and consideration.
