Jet Airways, SpiceJet, GoAir and IndiGo make up the grouping whose decision came a day after Air India lifted the flying ban imposed on the Lok Sabha member.
In a statement, FIA said its members are restoring the flying privileges to Gaikwad "under the assurance that our assets and colleagues shall be accorded the respect that they deserve for the hard work that they put in every day".
The decision has been taken consequent to Air India restoring flying privileges to Gaikwad after being satisfied with the statement given by him in the Lok Sabha where he expressed "regret" for assaulting an Air India staffer.
On Friday, sources had said the Civil Aviation Ministry asked Air India as well as other airlines to lift the ban imposed on Gaikwad citing the "undertaking of good conduct" given by him.
