Southwest to charge for kids flying alone, allow pets in cabin

Southwest Airlines, which has largely refrained from engaging in the airline extra-fee feeding frenzy, has decided to add a levy for children flying alone, double charges for third checked bags, and allow pets in the cabin for $75 each way.
Southwest, which prides itself on its "no hidden fee'' policy, will add a $50 round-trip service charge for children ages 5 through 11 flying alone, according to a report by Bloomberg News. The levy will apply to fares bought after June 1 for flights starting June 17. Most of the major carriers, including Delta, American, and US Airways, charge $100 each way.
Southwest, which lets travelers check two bags for free, will raise the fee to $50 for a third checked bag and for luggage weighing 51 pounds to 70 pounds. The changes take effect June 17.
Among the major carriers only Southwest and JetBlue don’t charge for a first checked bag, and JetBlue charges for second and subsequent bags.
