To require the Secretary of Transportation to implement changes to improve air transportation, and for other purposes.

Airline Consumer Protection Act of 2017 This bill directs the Department of Transportation (DOT) to issue a final rule to require an air carrier to: seek, for a delay exceeding three hours, a cancellation, or a misconnection as a result of circumstances within the air carrier's control, alternative transportation for a displaced passenger; and accept, for a reasonable fee, a displaced passenger from another air carrier or a passenger involuntarily denied boarding due to a lack of available seats. The Government Accountability Office shall submit a report that reviews airline computer network functions. Any air carrier schedule change resulting from a computer network disruption, security breach, or other inoperability may be considered an event within a carrier's control. DOT shall: publish a final rule to require an air carrier to submit to the Federal Aviation Administration a plan for restoring full functionality of its computer network systems in the event of a service disruption; establish an airline industry computer network resiliency working group; modify federal regulations to require each air carrier to adopt a contingency plan for any delay, cancellation, or misconnection affecting a passenger; and issue regulations to ensure that a ticketed passenger shall not pay a fee to select an alternative flight if the aircraft's lavatory is not functioning.
