Seem unpopular accesss policy change requiring flight segment from its own airline or partner flight, first announced from DL SkyClub has lead to similar policy change to the other two, effective Nov 1, 2019. AA announced restrictive lounge access policy on Oct 18, 2018, UA on November 6, 2018. Both will be effective Nov 1, 2019. DL policy change is effective Jan 1, 2019.
Any successful class-action fight from DL, UA, and AA lifetime member would definitely change or break the course for implementation.....Am hopeful someone will be successful in fighting this.
