Three Italian passport-holders landed at Delhi from Amritsar at 12.50am on 4 September on Air India 1115 and left for Munich at 1.45am on Lufthansa 763. The Ministry of Civil Aviation says they never completed departure immigration. The show-cause notice issued on 12 September to Air India, and addressed in reporting to chief executive Campbell Wilson, calls that a serious security and immigration-related lapse and a violation of the hub-and-spoke standard operating procedure. The airline has seven days to answer in writing. The Home Ministry called stakeholders in. Home Secretary Govind Mohan was due to chair a meeting on 15 September. Air India had not issued a matching public explanation when the notice first appeared. That is the official frame. These were domestic-to-international passengers treated as if they were already airside on an international-to-international transfer. Fifty-five minutes is not a long bank. It is long enough for a wrong corridor to become a departure.
The boarding documents carried a 'D' mark for the Amritsar-Delhi sector. Under the approved hub-and-spoke SOP, that mark should have sent them through a designated domestic arrival path, then out to immigration, then back into international departures. The airline is being asked about which prescribed door was Gate 39 in the immigration area. Instead it seems ground handling routed them into the I-to-I transfer zone. From there they reached the Lufthansa departure without an immigration stamp or an electronic equivalent. Both the Delhi and Munich boarding passes had already been issued in Amritsar. One passenger was described as wheelchair-bound. India had stopped physically stamping international boarding passes from 1 September. Officials have floated that change as a possible contributory factor, not as a completed finding. The ministry’s questions, as published, go to the chain rather than to a single clerk. Who let 'D' passengers into I-to-I. Why segregation by boarding-pass indicator failed. Who escorted them. Whether the general declaration, manifest and API-PNR data reached immigration in time. Why the breach was seen only after the aircraft had left. Those are the right questions. They are not yet answers.
The passengers have been named in some reports as Surjit Singh, Balwinder Kaur and Gurdev Singh. There is no public finding that they intended to evade control. The failure is the control chain. Airline departure control should have known a domestic arrival cannot board an international service without an exit record. Airport systems and Bureau of Immigration systems should have missed three bodies leaving the country. Lufthansa or its handler should have seen an uncleared status before the door closed. Whether an immigration or CISF post stood at that transfer junction at 1am is one of the facts Air India and DIAL now have to put on paper. How many domestic-to-international connections Air India turns at Delhi each night has not been published with this notice. The gap is not unique to one flight number. Any carrier that issues dual boarding passes at a spoke, then relies on a human escort through T3 in the small hours, is running the same junction. Hub-and-spoke only works if the spoke ticket does not pretend the passenger has already left India.
The transfer zone is the invisible border. A domestic arrival is still on Indian soil. An I-to-I sterile walk assumes the state has already seen the passport. Mix those two flows and the airport looks efficient until three people are in Munich and the file opens in Delhi. The show-cause is Air India’s. The audit belongs to every airline, handler and immigration desk that treats a 55-minute connection as proof that the border has already been crossed.
