Southwest Airlines Co. introduced a new bamboo cup for inflight cold beverages and a wood stir stick with the carrier’s iconic Heart branding. Both the new cup and stir stick are part of the carrier’s ongoing work toward its goal to eliminate, where feasible, single-use plastics from inflight service by 20301.
Southwest expects the new items to reduce its inflight single-use plastics by more than 1.5 million pounds annually2. The airline continues to explore new sourcing initiatives to address single-use plastic packaging across inflight operations as part of its Nonstop to Net Zero strategy, a key tenet of which is Circularity3.
Raising a Cold Cup: The new cold cup is made from 93 percent non-plastic materials, with a pulp blend consisting of 75 percent bamboo and 25 percent paper and a polyethylene (PE) lining. The U.S. Green Building Council considers bamboo a “rapidly renewable material”4 because it reaches maturity for harvest in three to five years.
Creating Quite a Stir: The new stir stick is made from 100 percent FSC5-certified birch wood and maintains Southwest’s iconic Heart branding.
Cleaning up Napkins: In July 2024, Southwest transitioned to a paper overwrap for its napkins made from 100 percent post-consumer recycled materials, fully eliminating plastic from this service item. The overwrap is made from FSC or PEFC5-certified materials.
Aloha, New Snack: In the coming months, Southwest will introduce a new select-a-snack offering on flights to and from Hawaii. This change is anticipated to decrease food waste and reduce single-use plastic packaging by at least 18,000 pounds annually.
Southwest analyzed the sustainability and environmental footprints of its inflight service items to identify opportunities for improvement. The carrier identified two of the largest sources of single-use plastics for inflight service: cups for cold beverages and stir sticks. Throughout 2024, Southwest developed an action plan to replace these items, which included robust testing among Customers and Employees.
“We expect our new bamboo cold cup, wood stir stick, and other initiatives to exceed our goal to reduce plastics from inflight service by 50 percent by weight by 2025, and we’re excited to continue collaborating with our suppliers to work toward our goal of fully eliminating, where feasible, single-use plastics from inflight service by 20306,” said Helen Giles, Managing Director of Environmental Sustainability at Southwest Airlines. “It’s been a year of work since we announced our Nonstop to Net Zero strategy, including our initiatives to tackle single-use plastics in our inflight service. The announcement celebrates the hard work and dedication of many Teams across Southwest to meet these goals.”
