Wow a la verdad q nos vieron la cara de bobos y nos cojieron de bobos tambien. Q trato mas injusto. No volveremos a viajar por AMERICAN AIRLINES asi mismo le dejaremos saber a todo el mundo el trato de esta linea con los pasajeros. Gracias a esto nos agravamos la espalda, costillas.

Despues q estabamos sentados en el avion el piloto no llegaba y nos tuvieron q bajar del avion, esperar a que llegara otro piloto para volvernos a montar en el avion!!! Q mala coordinacion!!
