Some airlines say they're getting squeezed by a shortage of limes.
A spokesman for United Airlines, which is part of United Continental Holdings, says the airline is currently flying with only 15% to 20% of its usual stock of limes.
"If the caterers are light on limes when they supply our flights, then we'll serve lemons," said Rahsaan Johnson. "We've asked them to continue to provide limes where available, but to cater more lemons until lime supplies normalize," he added.
"Apparently we go through 900 limes a day on flights, said Alaska Air spokeswoman Halley Knigge. "We're hoping to get them back on board when the case prices drop. We have not [had] any customer complaints. We've been serving lemons instead."
