Tex. Alcoholic Beverage Code § 22.03

(a) The holder of a package store permit or wine only package store permit issued for a location within a city or town or within two miles of the corporate limits of a city or town may make deliveries of and collections for alcoholic beverages off the premises in areas where the sale of the beverages is legal. The permittee must travel by the most direct route and may make deliveries and collections only within the county or the city or town or within two miles of its corporate limits, and only in response to bona fide orders placed by the customer, either in person at the premises, in writing, by mail, or by telegraph or telephone. This section shall not be construed as preventing a holder of a package store permit or wine only package store permit from delivering alcoholic beverages to the holder of a carrier's permit for transportation to persons who have placed bona fide orders and who are located in an area that the holder of a package store permit or wine only package store permit is authorized to directly deliver to under this section. The holder of a package store permit or wine only package store permit may also deliver alcoholic beverages to the holder of a carrier's permit for transportation outside of this state in response to bona fide orders placed by persons authorized to purchase the beverages.

(b) The holder of a package store permit may transport alcoholic beverages to a commercial airline in a regional airport located all or partly in an adjoining county if the airport is governed by a board, commission, or authority, some of whose members reside in the county where the package store is located.
