In response to long TSA security checkpoint wait times, several airlines have been working to help passengers get through the lines quicker.  Delta, American and United all offered their own resources to help the situation. Recently JetBlue announced that their top frequent flyers can apply for a free membership to TSA PreCheck.  Southwest is also now allowing their frequent flyer members to sign up for TSA PreCheck with a payment of 9,000 Rapid Rewards points, rather than the $85 fee required for the membership.
