Can you bring Contact Lens Solution on a plane?
Coop checked the book. Here's the ruling for Contact Lens Solution:
What the TSA says
TSA allows larger amounts of medically necessary liquids, gels, and aerosols in reasonable quantities for your trip, but you must declare them to security officers at the checkpoint for inspection. Any oversized medically-necessary liquids that alarm during screening, testing positive for certain chemicals, may not be allowed through the screening checkpoint. Some contact lens solutions contain chemicals that typically alarm and may not permitted through the checkpoint. We recommend placing contact lens solutions over 3.4 ounces in your checked baggage.
