Why internet users are asking — “Why were international flights not cancelled?”

International travel chaos often sparks one simple question on social media: if domestic schedules are disrupted, why aren’t international flights cancelled too? The recent turmoil around Indigo Flight operations in India has pushed that question into trending threads, with passengers, reporters and policymakers asking how airlines decide which services to ground and which to run. This article explains the decision-making behind cancellations, what happened with Indigo, and what flyers should know right now.

Short answer — different rules, different risks

Airlines treat domestic and international services differently. Cancelling a domestic flight is usually an operational decision — if there’s no crew, an aircraft problem, or airspace congestion, that specific departure is scrubbed. International flights, however, have additional regulatory, contractual and diplomatic layers, so they’re cancelled less readily.

Why? Because international services often involve slots at foreign airports, bilateral agreements, and crew/aircraft positioning that create ripple effects across borders. Cancelling them can strand people abroad, trigger cross-border liability rules, and require approvals from foreign authorities. In short: the threshold to cancel an international leg is higher than for a same-day domestic rotation.

What triggered the Indigo Flight crisis — and why domestic flights bore the brunt

New pilot duty rules reduced available crew unexpectedly

The immediate cause behind the recent wave of Indigo Flight cancellations was a sudden shortage of legally available cockpit crew after the rollout of updated Flight Duty Time Limitation (FDTL) rules. These rules increased mandatory rest and adjusted allowable duty windows for pilots — safety-driven changes that left some earlier rosters non-compliant overnight. Indigo said it had “misjudgment and planning gaps” while implementing the second phase of these rules.

Domino effect on domestic rotations

Because many domestic flights are short-turn rotations (aircraft fly multiple hops in a day), losing crew for one sector forces multiple cancellations. That’s why airports like Delhi and Mumbai saw hundreds of domestic departures cancelled in a single day. Domestic schedules are more vulnerable to rapid crew shortfalls.

So why were many international flights still operating?

Crew and aircraft already positioned for international legs

International routes often use crews and aircraft that are planned and positioned differently — sometimes with rest periods and stand-by crew arranged to meet both home and destination country rules. Airlines may have crews who completed mandated rest earlier or flights staffed by pilots whose rosters weren’t affected by the specific schedule clashes. In those cases, cancelling an international leg wasn’t strictly necessary.

Complex penalties, passenger welfare and diplomatic fallout

Cancelling international flights can mean heavier penalties, customer compensation complexities, and, in worst cases, diplomatic complaints if citizens are left abroad or foreign airports become congested. For many airlines, operating the international leg — even at reduced frequency — was less disruptive overall than cancelling and dealing with cross-border fallout. Economic Times and other outlets reported airlines balancing these commercial and operational trade-offs when deciding which flights to keep.

What the regulator did — and why it matters for passengers

DGCA intervention and temporary relief

India’s regulator, the DGCA, stepped in amid the chaos. It provided partial relief around some duty rules and asked airlines, including Indigo, to improve rostering and disruption management. These interventions aimed to stabilize schedules quickly while keeping safety standards intact. The DGCA also ordered inquiries and coordination with airports to reduce passenger hardship.

What that means for you as a traveller

Passengers should expect further short-notice domestic cancellations in the immediate days while airlines rebalance rosters. International services may remain relatively more stable, but don’t assume immunity: if the crew shortage deepens or aircraft availability falls, international flights could be affected too. Airlines are legally required to inform customers and offer rebooking or refunds where cancellations occur.

Practical tips if your Indigo Flight or other service is at risk

Before you travel

• Check your airline’s live status and the DGCA or airport advisories the morning of departure.
• If you have a tight international connection, consider moving to an earlier flight where possible.
• Have digital copies of travel documents and contact details for your airline and credit card provider.

At the airport or after a cancellation

• Request rebooking or refund options immediately; airlines often have priority re-accommodation for international passengers.
• Keep receipts for additional expenses — you may be eligible for compensation or reimbursement depending on the airline’s policy and the regulator’s direction.
• Follow official airline channels and avoid misinformation on social platforms. During large disruptions, unofficial posts can create confusion.

Bigger picture — safety vs. convenience

The Indigo Flight disruption highlights an important industry tension: safety regulation changes (like stricter rest rules) improve long-term safety but can cause short-term service pain if airlines’ planning doesn’t match the new limits. Regulators tend to prioritize safety; airlines must then rebuild schedules and crew pipelines to comply while minimizing passenger disruption. The current episode prompted DGCA action and promises from IndiGo about phased recovery and rostering fixes.

Final takeaway — informed travellers fare better

When social media asks, “Why weren’t international flights cancelled?” the answer is rarely simple. It’s a mix of regulatory thresholds, crew and aircraft positioning, commercial penalties, and passenger welfare considerations. The Indigo Flight crisis underlines how an operational gap in crew planning — especially after safety-driven rule changes — can rip through domestic networks, while international services may persist because cancelling them would cause broader cross-border complications.

If you’re traveling soon, keep an eye on official airline and airport updates, know your rebooking and refund options, and build buffer time into international itineraries where possible. That practical awareness is the best protection when aviation schedules are under stress.
