The decision of the Federation of Indian Airlines (FIA) comes a day after the national carrier, following direction from the civil aviation ministry, revoked the ban on Gaikwad.
The flying restriction on the Lok Sabha member has been lifted after he gave an undertaking that such incidents will not reoccur.
The FIA, which has Jet Airways, IndiGo, SpiceJet and GoAir as members, today said its members are restoring the flying privileges to Gaikwad.
In a statement, the grouping said it is being done after Air India lifted the ban and "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".
Vistara and AirAsia India are not part of the FIA.
In a series of tweets today, Minister of State for Civil Aviation Jayant Sinha said Air India was advised to lift the ban as Gaikwad had "apologised and provided undertaking that such incidents would not reoccur".
"Police investigations regarding Gaikwad's conduct during the March 23 incident are under way and the law will take its own course," Sinha said.
When the FIA had imposed a flying ban on Gaikwad, Vistara and AirAsia had said they were with the industry on the issue.
In a climbdown after combative Shiv Sena members disrupted Lok Sabha proceedings, Gaikwad on April 6 wrote a letter to Civil Aviation Minister Ashok Gajapathi Raju expressing "regret" over the "unfortunate incident".
He had also virtually given an undertaking that there would be no repeat of such incident and sought lifting of the ban.
