The meeting assumes significance as it comes days before Air India formally gets inducted as the 27th member of the global airlines' club, Star Alliance, later this week.
"Two pilot unions IPG and ICPA have been called by the management for a high-level meeting at the Airlines House on Monday," sources said.
While the full agenda of the meeting is not yet known, issues of integration of the unions and salary restructuring plans are expected to be discussed, they said.
Sources said the management, however, will be holding a meeting with the two unions Indian Pilots Guild (of Air India) and Indian Commercial Pilots Association (of erstwhile Indian Airlines) separately.
Both IPG and ICPA had in the past been on loggerheads, which had even led to an over two-month strike in the carrier two years ago.
"A committee under former labour secretary Krishna Mohan Sahni has recommended to have only three recognised unions at the national carrier, one each in Air India and its engineering and ground handling subsidiaries," sources said.
Besides, the issue of restructuring the salary is also likely to be discussed during tomorrow's meeting, they said, adding the management had come out with a plan in April but had to defer its implementation in view of the elections.
The induction into Star Alliance is expected to improve Air India's connectivity to high-growth economies and give the 26 Star Alliance members access to India's domestic aviation market.
