Air India vs SriLankan Airlines (2026): Which Should You Actually Book?

Two four-star subcontinent carriers, both pouring you a hot curry at 38,000 feet — but only one hands you 30kg and a free night in Colombo.

On paper these look like twins: both full-service, both Skytrax four-star, both serving a real hot meal in economy on a single 1-piece baggage fare. Look closer and they’re opposites. Air India (AI) is a €26-billion Tata reconstruction project — 82 destinations, 312 routes, a fleet of brand-new Adient and Recaro business suites arriving, and 4,403 price observations that put it in European deal feeds almost constantly. SriLankan (UL) is a boutique with one job: funnel the subcontinent, the Gulf and Europe through its Colombo (CMB) hub on 31 destinations and 62 routes. For an aifly reader booking the cheapest economy seat, the gap that matters isn’t the seat map — it’s the free 30kg bag, the free Colombo stopover, and which airline actually shows up on your route. Here’s who wins each fight.

The cheapest seat: 30kg vs 23kg, and who strips what

This is the fight aifly readers care about most, and SriLankan wins it cleanly. Its cheapest “Saver” economy fare includes 30kg of checked baggage in a single piece — unusually generous for a discount fare. Air India’s “Economy Saver” gives you 23kg, a full 7kg less, and its headline “two bags” allowance applies only on flights to and from North America — on Europe, UK and Asia routes you’re back to one 23kg piece. Both carriers charge for advance seat selection on the cheapest fare, and both peg change fees around €100, so neither is a trap there. Hand baggage tilts marginally to Air India (8kg vs UL’s 7kg). But for anyone packing a real suitcase — and most leisure travellers to Colombo or Kochi are — SriLankan’s extra 7kg is worth more than any onboard flourish. It’s free money at the bag drop.

SriLankan hands you 30kg and a free night in Colombo; Air India hands you a fleet of brand-new suites you might not actually be sitting in.

The free Colombo stopover — SriLankan's ace

Here’s the perk Air India simply can’t match: SriLankan runs a genuine free stopover programme in Colombo. Break your journey at CMB on the return leg of a trip to Southeast Asia, Europe, the Middle East, Japan or Australia, and if your transit runs 8 to 24 hours, SriLankan provides free hotel accommodation, meals and airport transfers. That turns a dead layover into a free night — and effectively a bonus destination — on the way home. It’s the kind of stopover play Gulf and Asian hubs built their brands on, and UL executes it quietly and well. Air India, despite its two hubs at Delhi and Mumbai, offers no equivalent stopover package — a transit through DEL is just a transit. If you’re the sort of traveller who’ll build a trip around a freebie, this alone can decide the booking in SriLankan’s favour.

Network & fleet: the reborn giant vs the island specialist

On raw reach it’s no contest. Air India flies 82 destinations across 312 routes from Delhi and Mumbai, feeds into 25 Star Alliance partners, and is midway through the biggest fleet renewal in its history — A350s, 787-9s, A321neos and 737 MAXs replacing tired old metal, with an average fleet age already down to nine years. It shows up as a bookable deal constantly (4,403 price observations in our data). SriLankan is the opposite bet: 31 destinations, 62 routes, all radiating from Colombo, on an ageing widebody backbone of A330-200s (fleet age ~10.5 years). It rarely surfaces as a European deal — just 255 observations — because it only flies a handful of long-haul routes (LHR, CDG) plus a dense Gulf and South-India web (COK, HYD, MAA, DOH, RUH). Air India is the everywhere airline; SriLankan is the Colombo specialist.

Reliability & the shadow of AI171

Punctuality favours the smaller carrier. SriLankan posted 70% on-time performance in Cirium’s 2025 annual figures against Air India’s 60% — a meaningful gap when a tight connection is on the line, and consistent with Air India’s own admission that reliability and mishandled-bag rates are still being rebuilt post-privatisation. Then there’s the elephant in the room: on 12 June 2025, Air India Flight 171, a 787-8 bound for London Gatwick, crashed seconds after takeoff from Ahmedabad, killing 260 people. The investigation centred on fuel-control switches moving to cutoff; Air India completed precautionary inspections across its 787 and 737 fleets. Statistically it does not make Air India an unsafe airline in 2026 — but it’s honest to say the carrier is flying under intense scrutiny while it rebuilds. SriLankan has a clean modern safety record. For nervous flyers, that’s a real, if emotional, factor.

One flies 312 routes; the other flies you to a free hotel in Colombo.

Cabin & food: new suites you might not get vs consistent hospitality

Air India’s premium cabin is genuinely exciting — and genuinely inconsistent. The new 787-9s carry Adient “Ascent” reverse-herringbone suites with doors, and the incoming A350-1000s get Recaro R7 staggered suites; when you land one, it’s world-class. But retrofits are mid-rollout, so an identical route can serve you a decade-old recliner instead — the aircraft can swap under you. SriLankan makes no such promises and breaks none: lie-flat business on the A330-300s, angled seats on older jets, and a cabin experience defined less by hardware than by warm Sri Lankan service. Down in economy, both give you 4-star seatback screens and a real hot meal — Air India at a slightly tighter 31″ pitch, SriLankan at a roomier 32″. SriLankan’s authentic Sri Lankan curries are a quiet highlight. Verdict: Air India for the ceiling, SriLankan for the floor you can count on.

Wi-Fi, alliance & the everyday extras

Connectivity is the one clear win for Air India. It’s rolling out paid broadband wi-fi at cheap rates across renewed aircraft, so you can actually work aloft. SriLankan is stuck in the past here — no wi-fi on most of the fleet (only a legacy OnAir system on some A330-300s, and no Starlink on the horizon). If staying connected matters, Air India wins outright. On alliances it’s a philosophical split rather than a winner: Air India sits in Star Alliance with its overhauled Maharaja Club programme and a shiny new flagship Maharaja Lounge at Delhi T3 (opened February 2026); SriLankan is a long-standing oneworld member with FlySmiLes (~800,000 members) and the intimate Serendib Lounge at Colombo. Pick by the alliance you already collect in — Qatar/BA/Cathay flyers lean UL, United/Lufthansa/Singapore flyers lean AI.
