DOH - PHL

American does not provide a comparable level of onboard service to business class passengers compared to what used to be provided by Qatar Airways on the same route between DOH and PHL. American's flight attendants do the minimal to make business class passengers feel welcome; they provide less attentive and less friendly service compared to other international carriers such as Emirates and Qatar Airways.
