IndiGo vs Xiamen Airlines (2026): Which Should You Actually Book?

One hands you a 30-kilo bag and a hot meal on the cheapest international ticket in the sky; the other hands you a free hotel in China — and almost never both.

On paper this looks lopsided: IndiGo (6E) is India’s giant, an 83-destination, 366-route machine flying the newest narrowbodies off the line — A320neo, A321neo, and the range-stretching A321XLR now reaching Athens and Istanbul. Xiamen Airlines (MF) is a 42-destination SkyTeam boutique built around its Xiamen (XMN) hub and a 737-MAX fleet. But the numbers that decide a booking don’t move the way you’d expect. IndiGo is technically the “classic” (unaligned, no seatback screens, no wifi) carrier; Xiamen is the four-star full-service one. Yet IndiGo’s cheapest international Economy fare quietly includes 30kg of checked baggage across up to two pieces, while Xiamen’s includes 23kg in one. For a European flyer hunting a cheap seat, that inversion — plus a free Chinese stopover only one of them offers — is the entire story.

Two carriers, a continent apart

These airlines barely compete for the same passenger, and that’s the first thing worth knowing. IndiGo runs 366 routes to 83 destinations out of a Delhi (DEL) and Mumbai (BOM) double hub, and its top international lanes — Athens, Istanbul, Manchester, Amsterdam, Colombo, Phuket — read like a carrier aggressively colonising the Europe–India and India–Southeast Asia corridors. Xiamen is a fraction of the size: 110 routes, 42 destinations, anchored on Xiamen (XMN) with secondary bases at Fuzhou (FOC) and Hangzhou (HGH). Its long-haul map is thin and Chinese-centric — Amsterdam and Madrid into Europe, Melbourne and Sydney into Australia, Manila across Asia — mostly one-frequency threads back to the mainland. So the honest framing isn’t “which is better” but “where are you going?” If your itinerary touches India, IndiGo has the density; if it touches China, Xiamen has the feed. The overlap is nearly zero, which makes the fare mechanics below the real battleground.

IndiGo gives you the bag; Xiamen gives you the bed — in a free Chinese transit hotel.

The cheapest fare: where IndiGo quietly wins

This is the section aifly readers care about, and it flips the star ratings on their head. Both airlines include a checked bag on the cheapest international Economy ticket — already a win over Europe’s hand-only ULCCs — but IndiGo is markedly more generous: 30kg spread across up to two pieces versus Xiamen’s 23kg in a single bag. Neither gives you free advance seat selection, and change fees are close (IndiGo about €80, Xiamen about €100). The deeper edge is availability. Our price tracker holds 5,930 IndiGo observations against just 308 for Xiamen — IndiGo turns up as a bookable deal an order of magnitude more often, because it floods the Europe–India market, while a Xiamen bargain is a rare sighting. We won’t quote a headline long-haul price (the floor figures include short domestic hops), but qualitatively: IndiGo is the one you’ll actually find on sale.

Xiamen's ace: a free stopover IndiGo can't touch

Here’s where the smaller carrier lands a punch the giant simply can’t. Xiamen leverages China’s 240-hour (10-day) visa-free transit and layers its own free transit-hotel programme on top: connect through Xiamen, Fuzhou, Quanzhou, or Hangzhou with a layover between 6 and 24 hours and you can claim a complimentary hotel night at the airline’s interline transit counter on arrival. That turns a dead connection into a free evening in coastal Fujian — a genuine trip enhancer, not a marketing asterisk. IndiGo offers nothing of the sort; it has no stopover product, no free-night scheme, and India’s visa rules give no equivalent transit grace. If you were weighing a routing purely on “what do I get for my layover,” this is a decisive, tangible perk. It’s the single best reason a leisure traveller might deliberately choose the Xiamen itinerary over a faster, cheaper alternative.

Screens, wifi, and the two inches that matter

Cabin comfort is the one place Xiamen’s four-star Skytrax rating earns its keep. It fields seatback screens and paid broadband wifi that’s cheap by industry standards — you can actually watch a movie and message home. IndiGo does neither: no seatback IFE, no wifi at all, just a bring-your-own-device Bluebox streaming server on its newest jets. Pitch also splits their way — Xiamen’s 31 inches versus IndiGo’s tight 29 — though both sit at a narrow 17-inch width, so shoulders lose either way. That gap shows in our comfort model too (Xiamen’s AFR 67 to IndiGo’s 56). The catch: IndiGo’s shortcomings are the classic-LCC trade you accept for the bag and the price, and its A321XLR long-haul cabin is newer and quieter than Xiamen’s ageing 737 interiors. For a red-eye you’ll notice Xiamen’s screen; for a four-hour hop the two inches matter more than the entertainment.

One shows up in 5,930 tracked fares, the other in 308. For a European flyer, that gap is the comparison.

Food, fleet, and what "business" really means here

Good news on catering: both include a hot meal in Economy, so neither leaves you buying a sandwich. Both fleets are genuinely young — IndiGo averages 6.5 years on its A320neo family, Xiamen about 7 on its 737-MAX — so you’re on modern metal whichever you pick. The divergence is at the front. Xiamen’s “Business Class” on the 787-9 widebody is a proper 1-2-1 lie-flat with pyjamas and amenity kits on long-haul; on its narrowbodies it’s a domestic-style recliner. IndiGo’s IndiGoStretch is newer and narrower in scope — a generous recliner (up to 38-inch pitch) with priority check-in and a bumped 40kg baggage allowance, currently on Delhi–Mumbai and the A321XLR runs to Athens and Istanbul — but be clear-eyed: it is not a flat bed. If lie-flat is your bar, Xiamen’s 787 wins; if you want a comfortable upgrade on an India route, Stretch is the smarter buy.

Alliance, points, and a dead-heat on reliability

If you collect miles, Xiamen is the obvious pick: it’s been a full SkyTeam member since 2012, so you earn and burn with KLM, Air France, Delta, and Virgin Atlantic, and its Egret Miles programme plugs into that web. IndiGo remains deliberately unaligned — no alliance, just a growing lattice of codeshares with Delta, KLM, Turkish, Qatar, and Virgin — and its own BluChip loyalty scheme only launched recently, so cross-crediting is still immature. On the metric that ruins trips, they’re a genuine tie: both posted 82% on-time performance in Cirium’s 2025 annual ranking, and both run tight, well-drilled hub operations (IndiGo at DEL/BOM, Xiamen at XMN) with strong safety records. So loyalty is the tiebreaker: SkyTeam flyer, lean Xiamen; frequent India traveller banking IndiGo BluChips, stay 6E.

So — which one?
