The USDOT issued FAQs on Aug 19, 2011 (last revised Dec 12, 2016) regarding enforcement of the Second Final Rule on Enhancing Airline Passenger Protections (EAPP #2). EAPP #2 includes the “Full Fare Rule” (Price Advertising and Opt-Out Provisions 14 CFR 399.84, published Dec 20, 1984), requiring fares advertised to include fees and taxes.


Customize “fares from” disclosure, as well as the fare timestamp and terms and conditions below each airModule.
Change the titles of airModules to reflect “fares seen by others” and/or Terms and Conditions before fares are presented to the web visitor.
“Prompt action” will depend on the type of advertisement. If it is a print advertisement, the print ad must be pulled as soon as practically possible. If the advertisement is an Internet banner ad on the carrier’s own website, the ad must be pulled as soon reasonably possible, which should be quickly, e.g., within 24 hours or less. If the Internet banner ad is on another website, the Enforcement Office realizes it may take more time to pull that ad, but such an ad should be pulled or modified as soon as possible (in no case in more than a day or two). In Internet fare listings the available fare must be updated immediately. For fare specials that are posted on Twitter or Facebook, as soon as there is no longer a reasonable number of seats available at those fares, the Twitter feed and Facebook feed should be updated to reflect that those fares have sold out, or the Twitter posting or Facebook posting should be removed from the carrier’s feed.
