I Tried to Profit From Flight Delays Using Data

A few months ago, a friend of mine had a SpiceJet flight get delayed for so long that she learned a new language, finished a novel, and made two lifelong friends at the airport Café Coffee Day. She got ₹10,000 as compensation which, coincidentally, was more than she paid for the ticket.

This made me wonder: can you get rich, or at least get your chai money back, by booking flights that are likely to be delayed?

The answer, according to math and a dangerous amount of free time, is: in a very specific case involving SpiceJet, a foggy winter morning in Patna, and a pilot who might be "too tired" maybe.

Let's crunch some numbers.

First, What Are India's Delay Compensation Rules?

Under DGCA's Civil Aviation Requirements (CAR Section 3, Series M, Part IV), Indian domestic airlines must compensate passengers for delays of 2 hours or more. The amount ranges from ₹5,000 to ₹20,000, depending on flight block time and how catastrophically late the airline decides to be.

Unlike EU rules (which sound positively luxurious at €250–€600), India's compensation is, let's say, humble. ₹10,000 is basically the cost of your airport samosa combo, duty-free chocolate, and one book you'll never finish.

But here's the catch: weather delays don't count. Which in India means fog season (November–February) is simultaneously the most likely time to be delayed and the least compensable. Classic.

So to be profitable, we need:

Probability of delay × Compensation > Ticket price

Because ticket prices need to be very low and delays need to be very frequent, we're going to look at the four main airlines flying Indian skies: IndiGo, SpiceJet, Air India, and Akasa Air.

(Yes, Air India has technically been reborn under the Tata Group. We're including it anyway because the past haunts us all.)

Drop a comment below with your worst Indian airline experience. Bonus points if it involves a pilot announcing the delay "due to operational reasons" at 11 PM and then the flight quietly disappearing from the board.

The Data

Using DGCA's monthly on-time performance reports and flight history data, we looked at domestic airline performance over the last few years.

Here's what we found:

IndiGo has about 60%+ market share and, until its spectacular December 2025 meltdown (more on that shortly), had the best on-time performance at around 74.85% for the Jan–Oct 2024 period. That means roughly 1 in 4 IndiGo flights is delayed — but most delays are short and won't hit compensation thresholds.

Akasa Air surprised everyone by being the most punctual airline in India, clocking ~83.7% on-time performance in 2023. Nobody hates Akasa Air yet, which means it's probably doing something right.

Air India came in at a middling 63.48% — a slight improvement over its government-era reputation of "we'll get there when we get there, this is a sovereign nation."

And then there is SpiceJet, which achieved a remarkable 48.61% on-time performance in 2024. That means more than half of SpiceJet flights were late. If SpiceJet were a student, it would be the one who submits assignments two weeks after the semester ends and still somehow gets a passing grade.

SpiceJet is, statistically speaking, your best bet for delay compensation.

The Airports: Where Chaos Lives

Not all airports are created equal. Some are models of efficiency. Others are, let's say, character-building experiences.

The usual suspects for delays include:

• Patna (JAY Prakash Narayan Airport): Famous for fog so thick in winter that airlines require 1,200 meters of visibility to operate — and frequently don't get it. Also famous for one incident where an IndiGo pilot announced he was "too tired to fly" at midnight and caused a passenger sit-in. Iconic.

• Bagdogra (IXB): The Air India Express Delhi–Bagdogra route has clocked delays of over 3 hours on multiple occasions. The DEL-IXB route has a punctuality rating of around 53% for departures. You're basically flipping a coin.

• Varanasi & Ayodhya: Frequently appear in cancellation bulletins. Perhaps the universe is telling you to take the train and find inner peace along the way.

• Srinagar: Weather + security + mountain geography = a scheduling nightmare. The stars must align for a Srinagar flight to depart on time.

• 
  

Meanwhile, Mumbai, Bangalore, and Delhi — despite being terrifyingly busy — are actually better-managed and thus worse for your delay-profit scheme. Sorry.

The Big One: The IndiGo December 2025 Disaster

If you want a case study in maximum delay probability, look no further than December 2025.

IndiGo — the airline that controls 60%+ of India's domestic market — completely failed to implement new FDTL (Flight Duty Time Limitation) rules requiring pilots to get more rest. The result? A cascading collapse of epic proportions.

Over 10 days:

• 4,500 flights cancelled

• 10 lakh+ passengers stranded

• ₹24 crore+ spent on compensation

• DGCA fined IndiGo ₹22.2 crore

• IndiGo issued a public apology, which is the aviation equivalent of your food delivery app texting you "we're sorry" after your biryani arrives cold

For passengers who were caught in this chaos and knew their rights? They walked away with real money. Those who didn't know their rights got a voucher for a complimentary snack box, which IndiGo had probably already run out of.

Running the Model

If we set up a simple expected value model like our EU counterparts:

Airline	Approx. Delay Rate (compensation-eligible)	Max Compensation	Expected Value per Ticket
IndiGo	~5–8% (normal); chaos events higher	₹10,000–20,000	Low (too expensive normally)
SpiceJet	~15–20%	₹10,000	Moderate
Air India	~10–12%	₹20,000	Moderate
Akasa Air	~5–7%	₹10,000	Low

The key insight: SpiceJet + a winter morning route + Patna or Bagdogra = your highest probability scenario.

SpiceJet tickets on the Delhi–Patna route have been available for as low as ₹1,500–₹2,500. With a ~15% chance of a compensable delay at ₹10,000, your expected value is roughly ₹1,500 — nearly breaking even before you even get on the plane.

If you're flying in December–January when fog is rampant (but remember, fog doesn't qualify), or if you catch SpiceJet on a bad operational day, your real-world probability can shoot even higher.

The Catch (There's Always a Catch)

Here's where I have to be honest with you, like a relative who ruined your career optimism at a family dinner.

1. Indian airlines are legendary at not paying up. IndiGo spent just ₹18,000 on compensation in all of 2022, despite thousands of cancellations. Air India has been fined multiple times for simply refusing to give passengers hotel rooms or money they're legally owed. Claiming compensation involves: finding the right form, submitting it, waiting, following up, waiting more, escalating to DGCA, and still possibly getting a voucher.

2. The amounts are small. ₹10,000 sounds okay until you factor in that you spent ₹400 on airport parking, ₹300 on chai and biscuits while waiting, and 6 hours of your life that you will never get back.

3. Extraordinary circumstances. Airlines love this clause. Fog? Extraordinary. Air Traffic Control? Extraordinary. The pilot "feeling unwell"? Extraordinary. The airline having bad vibes? Probably also extraordinary.

The Verdict

Can you profit from Indian flight delays?

Technically, yes. If you book a SpiceJet flight from Delhi to Patna on a foggy January morning, pray the fog clears just enough for the flight to attempt departure (so it's not weather-related), and then get delayed for 2+ hours due to operational reasons, you stand a reasonable chance of walking away with more money than your ticket cost.

Practically speaking, you will spend this money on airport food, lose a day of your life, and develop a deeply personal relationship with a blue plastic chair.

But unlike the EU, where a delay gets you a cheque for €600 and some dignity, in India, the real compensation is the friends we made while queued up at the airline counter for four hours — and the phone numbers we exchanged to file a collective DGCA complaint.

Travel safe. Carry snacks. Know your rights.

And maybe just take the train.
