American Airlines' bag delivery service is one of the best new airline perks around, says Travel and Leisure magazine.
For $29.95 US, passengers can have a bag delivered anywhere within a 64-kilometre radius of an airport, within four hours of landing. If the destination exceeds that distance, there's an extra charge and delivery could take up to six hours.
Another top perk: On Spanish airline Vueling, travellers can pay $78 US to be guaranteed a vacant seat beside them on national flights or $90 US on international flights.
