DGCA monthly on-time performance data for 2025-26 puts IndiGo consistently in the 80-85% range for domestic departures, while SpiceJet hovers around 65-70%. That gap is meaningful — but it doesn't mean you should never fly SpiceJet. The real question is when the fare difference justifies the delay risk.
TL;DR — the DGCA numbers and what they mean
Based on DGCA monthly performance reports for 2025 and early 2026, IndiGo's on-time performance (OTP) typically runs around 80–85% on domestic routes, making it the most reliable Indian carrier by volume. SpiceJet's OTP has been significantly lower — often in the 65–70% range — a gap that reflects its ongoing operational pressures. Air India has been improving (roughly mid-70s%), Air India Express and Akasa Air sit in broadly similar territory. This article breaks down what those numbers mean in practice, what DGCA's complaint data says, and how to factor this into your booking decision.
Note: DGCA publishes OTP data monthly. Always verify the current figures at dgca.gov.in before making decisions based on the most recent period.
How does DGCA measure on-time performance?
Before we look at numbers, it's worth understanding what DGCA's OTP actually measures — because the methodology matters for how you interpret it.
DGCA defines an on-time departure as a flight departing within 15 minutes of its scheduled departure time. OTP is calculated as the percentage of flights that meet this threshold across all domestic scheduled operations. The data is published monthly and covers all major domestic carriers — IndiGo, Air India, Air India Express, Akasa, SpiceJet, and others operating at the time.
What DGCA's OTP doesn't capture directly: arrival delay (a flight can depart on time and arrive late if there's an en-route or ATC hold), cancellation rates (tracked separately), or the severity of delays in the 85–15% that miss the 15-minute window. A 16-minute departure delay and a 4-hour delay both count as 'not on time' in the headline figure.
That said, the departure OTP is a reasonable proxy for airline operational discipline — an airline with consistently high departure OTP has its scheduling, ground handling, crew rostering and maintenance cycles under control. An airline with 65% OTP has a structural problem, not a bad-luck streak.
What the 2025-26 DGCA data shows for IndiGo
IndiGo consistently leads the domestic OTP chart in recent DGCA reports, typically posting OTP figures in the 80–86% range on a monthly basis. This is the best sustained performance of any high-volume Indian carrier — and it's all the more notable because IndiGo operates the most flights. At roughly 55–60% domestic market share, IndiGo's OTP is not the result of flying only easy routes or peak hours. They fly everywhere, at all hours, with a single narrowbody fleet (primarily Airbus A320 family).
IndiGo's OTP has held up even through ATR fleet issues, monsoon seasons, and the general chaos of Indian airport congestion. The reasons are operational rather than lucky: single fleet type (fewer maintenance permutations), high aircraft utilisation (planes don't sit idle), and a culture of quick turnarounds. They have been known to deplane passengers who board late — if you've heard that story from friends, it's true. They're not apologetic about it. Operationally, it works.
For travellers: booking IndiGo for connections, morning departures that cascade across a day's itinerary, or time-sensitive travel (job interviews, visa appointment, wedding) is the lowest-risk domestic choice in India right now.
What the DGCA data shows for SpiceJet — and why
SpiceJet's OTP in recent DGCA data has been markedly lower — around 65–72% in many recent months. That means roughly one in three SpiceJet flights departs more than 15 minutes late. Compare that to IndiGo's roughly one in six, and you start to feel the operational gap.
Why is SpiceJet's OTP this low? The honest answer is the carrier has had persistent financial and operational difficulties. SpiceJet faced fuel non-payment crises, aircraft groundings due to maintenance disputes, and at points in 2022–24, had to significantly shrink its fleet. Some of that has stabilised, but the legacy of a smaller, more stretched fleet with older aircraft and supply-chain issues doesn't get fixed overnight. When any aircraft has an unscheduled maintenance requirement, the ripple effect across a lean schedule is severe — and SpiceJet's schedule in 2025–26 is lean.
DGCA also publishes passenger complaint data. SpiceJet has historically featured prominently in complaints per 10,000 passengers — for both delays and cancellations. The complaints per passenger figure is worth checking alongside OTP because it captures consumer experience, not just departure timing.
Caveat: SpiceJet's situation has been evolving. If you're reading this in mid-2026, check DGCA's latest monthly report for the current figures — the airline's performance can shift as its financial situation changes.
Air India, Akasa, and Air India Express — where do they sit?
To contextualise the IndiGo-SpiceJet comparison, a quick read on the other carriers:
Air India: Post-Tata Group takeover and the merger of Vistara (which ceased as a separate entity in late 2024 and was absorbed into Air India), OTP has been on an improvement trajectory. Recent DGCA reports typically put Air India in the mid-70s to low-80s percentage range for domestic routes. The integration of Vistara's slots and crew has been disruptive in patches, but the overall direction is upward. For premium travel on domestic routes, Air India is increasingly competitive.
Air India Express: The low-cost arm covers both domestic routes and short-haul international. OTP has been variable — the 2024 crew sick-call crisis that grounded flights briefly was a significant disruption, but the airline has since stabilised. Broadly similar to Air India's domestic figures in recent months.
Akasa Air: The youngest major carrier, operating a fleet of Boeing 737 MAX aircraft. Akasa's OTP has generally been decent — around 75–82% in recent reporting periods — for a young airline still ramping up. Worth watching as it adds international routes and scales.
When is SpiceJet's lower fare still worth choosing?
Here's where I'll give you the practical take, not just the data dump. SpiceJet is not always the wrong choice. There are specific scenarios where accepting the higher delay risk makes sense:
- No onward connection or tight schedule: If you're flying SpiceJet for a leisure trip where being 2 hours late doesn't ruin anything — a weekend in Bengaluru, a flight home for a family visit — the fare saving is real and the consequence of a delay is low.
- Fare gap is large: If SpiceJet is ₹3,000 cheaper on a route and the IndiGo flight doesn't have a meaningful timing advantage, the math might work for you. A 35% OTP gap translates to roughly 1 in 5 additional delay events — is ₹3,000 worth absorbing 1 in 5 bad experiences? Personal call.
- Specific routes where SpiceJet is the only meaningful option: On some Tier-2 to Tier-2 city routes, SpiceJet and IndiGo may be the only airlines, or SpiceJet's timing is substantially better for your schedule. In that case you have less of a choice anyway.
- Never for same-day international connections: If you're catching an international flight on the same day, do not book SpiceJet as the domestic feeder leg. The delay risk is too high to absorb. Book IndiGo or fly the previous day with a hotel buffer.

Passenger rights: what are you entitled to if your IndiGo or SpiceJet flight is delayed?
DGCA's Civil Aviation Requirements (CAR) on Passenger Rights apply to all domestic scheduled carriers. Key entitlements:
- Delay of 2+ hours: The airline must offer meals and refreshments at the airport.
- Delay of 24+ hours: Full refund or rebooking on the next available flight at no extra charge.
- Cancellation with less than 2 weeks' notice: Option of full refund or rebooking.
- Denied boarding due to overbooking: Compensation in the range of ₹10,000 or 200% of the booked one-way fare (whichever is lower), plus the option of a refund or alternate flight.
In practice, enforcement varies. Airlines — including IndiGo — do not always proactively offer what they're required to under the CAR. If you're denied boarding or face a significant delay, file a written complaint with the airline first and then escalate to DGCA's complaint portal (https://dgca.gov.in) if unresolved. Keep your boarding pass and all communication. The AirSewa app (by MoCA/DGCA) is another channel for formal complaints against Indian carriers.
Bottom line
The DGCA data makes a clear case: IndiGo is India's most reliably on-time domestic carrier at scale. For time-sensitive travel, connections, or any trip where a 3-hour delay would cause real problems, IndiGo is the lower-risk choice and worth a fare premium. SpiceJet's OTP gap is not a fluke — it reflects structural operational challenges that a fare saving of ₹1,000–₹2,000 may or may not justify depending on your trip. Use the numbers, factor in what a delay would actually cost you in time or money, and book accordingly.

Frequently asked questions
What is IndiGo's on-time performance in 2026?
Based on recent DGCA monthly reports, IndiGo's domestic OTP has been running in the 80–86% range in 2025–26, making it the most consistently punctual high-volume carrier in India. Verify the latest monthly figure at dgca.gov.in as DGCA updates data monthly.
What is SpiceJet's on-time performance in 2026?
SpiceJet's OTP in recent DGCA data has typically been in the 65–72% range — roughly 10–18 percentage points below IndiGo. This reflects ongoing operational and fleet challenges. Always check the latest DGCA monthly report for current figures, as the airline's performance can shift.
Which Indian domestic airline has the best on-time record?
IndiGo leads in recent DGCA reports, followed by Air India and Akasa Air in the mid-70s to low-80s range. Air India Express is broadly similar to Air India. SpiceJet has been the lowest-performing major carrier in recent periods. Vistara no longer exists as a separate entity — it merged into Air India in late 2024.
What can I claim if my domestic flight is delayed in India?
Under DGCA's Civil Aviation Requirements, a 2+ hour delay entitles you to meals and refreshments. A 24+ hour delay triggers full refund or free rebooking rights. Denied boarding due to overbooking entitles you to compensation — typically ₹10,000 or 200% of one-way fare, whichever is lower. Escalate to DGCA's AirSewa portal if the airline does not comply.
Should I choose IndiGo over SpiceJet even if SpiceJet is cheaper?
It depends on how much a delay would cost you. For same-day international connections, important meetings, or weddings — always choose IndiGo. For leisure travel with no tight onward connection, a SpiceJet fare that is ₹2,000–₹4,000 cheaper may be worth the delay risk. Never book SpiceJet as a domestic feeder for a same-day international departure.
Does Air India have better on-time performance than IndiGo?
In recent DGCA data, IndiGo's OTP is typically slightly higher than Air India's on domestic routes, though Air India has been on an improvement trend post-Tata takeover and the Vistara merger. Air India tends to have better inflight service and more seat comfort at comparable fares — so it depends on whether you prioritise punctuality or the onboard experience.
