"Although we look forward to working with the authorities to resolve these issues quickly, this unwarranted action by authorities to punish drivers and riders cannot continue," Uber spokesman Andrew Noyes wrote in a company blog post a week ago. "That's why we're temporarily halting uberX pick-ups at LAX effective immediately."

Noyes told CNBC there were no projections on when the uberX pickup service might resume, but that for now uberX drivers are still dropping off passengers at LAX. The company's other services, UberBLACK and UberSUV, which work with licensed commercial drivers, continue both pickups and dropoffs at LAX, he said.

Sidecar spokeswoman Margaret Ryan said via email that because the company has heard of the increased enforcement action at LAX, "we've advised Los Angeles drivers to avoid picking up passengers at LAX as well."
In an email, Los Angeles Airport Police spokeswoman Sgt. Belinda Nettles said "no special enforcement is taking place" against uberX, Sidecar or other ride-share drivers. Only that "airport police officers are enforcing airport rules and regulations, as well as any violations pertaining to the penal code, vehicle code and the Los Angeles municipal codes as appropriate."
At issue are the first round of rules issued by the California Public Utilities Commission for regulating companies such as Uber, Sidecar and Lyft, which the commission calls transportation network companies. "The question of picking up passengers by TNCs is still under review" by the commission, and TNCs wishing to serve the airport also need licenses or permits, and insurance, to do business at LAX, Nettles said.
Nettles said Thursday she was unable to provide information on what types of citations were issued to uberX drivers. "We cite for airport rules and regulation violations and California vehicle and penal code violations as appropriate daily," she said.
LAX is not the only airport that has taken action against ride-sharing companies.
In April, San Francisco International Airport issued a cease and desist order to ride-sharing services operating there. "These were enforced primarily through admonishments, and some citations were also issued," said SFO spokesman Doug Yakel.
Like many other airports, San Francisco has rules stating that each business that provides ground transportation, rental car or airport parking services must get an airport permit .
In response, Uber published a blog post in August with tips for riders at SFO noting that pickups by Uber services were unaffected, but that "SFO has taken an aggressive stance against uberX and has begun citing some drivers." The company suggested fliers instead use another Uber ride service, such as UberBLACK or UberSUV.
