Thirteen of these crew members have "tendered an unconditional apology and blamed the union for misleading them", the airline said in a statement here.
The crew members "have also given in writing that they will follow the FDTL, roster and assigned duties as per the company's requirements. However, the management has not taken any decision on the issue so far", it said.
The management recently held a round of talks with the All India Cabin Crew Association (AICCA) on the issue they were protesting but no conclusion has been reached, airline officials said.
While sacking them, Air India had said it had been "asking them to follow FDTL rules for over six months but they failed to do so and this forced the management to take this extreme step".
FDTL norms are guidelines governing issues like maximum daily flight duty period, including flying hour limitations, rest period, staff-on-duty travel and number of landings allowed per pilot as well as the crew.
