Hendy (pictured), who has been instructed by Thompsons Solicitors partner Neil Johnson, is representing the Unite union. He is leading Marcus Pilgerstorfer, also of Old Square.
Carr, who is leading Paul Gott of Fountain Court Chambers, has been instructed by Baker & McKenzie partner John Evason for BA.
BA has taken legal action after its cabin crew voted overwhelmingly in support of 12-day strike action beginning on 22 December.
The airline is seeking an injunction to prevent the strike going ahead, claiming there were irregularities in the strike ballot that meant staff member who had already been made redundant were allowed to vote on the action.
Cabin crew voted to strike after BA refused to suspend new contractual arrangements.
As reported on TheLawyer.com last month, Hendy was originally instructed by Unite to argue that by imposing new employment terms on its 14,000 cabin crew members BA was in breach of contract (4 November 2009).
The matter was due to be heard in the High Court in November, but was stayed until February.
On that occasion Hendy was instructed by partner Steve Cottingham at trade union firm OH Parsons & Partners. BA turned to Evason at Bakers, who instructed Devereux’s Timothy Brennan QC.
