Airlines are always making changes to cut costs and attract more customers. This week two major airlines announced some plans that will enthrall some travelers and have others gate-checking their extra luggage.

Customers asked American Airlines to bring back free beer and wine to international flights, and the company listened. Complimentary adult beverages will be served in all classes between the US and Europe, Asia, and some Latin American destinations. The free beer and wine service will begin February 1st.

American Airlines will continue to offer liquor for purchase on international flights, and the amount of free beer and wine served to passengers is up to the flight crew.

Southwest Airlines is changing the interior of planes in its fleet as well as planes acquired through the purchase of Air Tran last year. Plans for the aircraft include replacing the current seats with lighter seats covered in a more durable material, more under-seat stowage space, a reduction of reclining from three inches to two inches, the addition of six more seats to each plane, and recycled carpet. The new cabins will be installed starting in March and will be used on high-demand routes in and out of Las Vegas.

Fuel saving from the lighter seats is expected to save Southwest $10 million a year, and the extra six seats per aircraft could add $250 million annually.

The announcement has met with some dissatisfaction--while Southwest is reducing the weight of the plane and carbon emissions, travelers will have less legroom, less room to recline their seats, and a harder fight for space in the overhead bin. The competition for storage is difficult as it is--adding six more suitcases to the mix each flight isn’t going to be good.
