At midday Wednesday, shares of American Airlines Group Inc. were down $1, or 2.3 percent, to $42.66; United Continental Holdings Inc. fell $2.04, or 4.3 percent, to $45.72; Delta Air Lines Inc. dropped $1.47, or 3.5 percent, to $40.45; and Southwest Airlines Co. lost 27 cents to $27.02.
Lufthansa AG cut its forecast of 2014 and 2015 operating profit on weaker demand, strikes, and lower value of Venezuela's currency. Its shares were down 14 percent.
Cowen and Co. analyst Helane Becker says the warning is more about Lufthansa's prospects than the airline industry, and she says the sell-off could be an opportunity for buyers.
