While Frontier Airlines maintains a list of requirements for all carry-on luggage, they do not have their own regulations regarding liquids. Instead, Frontier Airlines is bound by the regulations set forth by the Transportation Security Administration (TSA.)

Acceptable Items

According to the TSA, liquids, aerosols and gels are acceptable on board airplanes. However, the quantity of the items are subject to limitations set forth in the "3-1-1 Rule."


TSA's 3-1-1 Rule

TSA's guideline regarding carry-on liquids states that a passenger may bring aboard liquids contained in 3.4 ounce (or less) bottles. The bottles must be placed in a one-quart, clear, plastic, zip-top bag. Passengers are limited to one bag each.



Liquids such as medications, baby formula and food and breast milk are allowed in reasonable quantities, even if these quantities exceed the 3.4 ounce guideline. To avoid delays, the passenger must declare these items for inspection at the checkpoint.
