Post-AIX-Connect merger, Air India Express is a meaningfully better product than the old AI Express most flyers remember. Here is how it stacks up against the IndiGo gold standard in 2026.
Quick answer
For pure on-time domestic short-haul, IndiGo still wins — fewer cancellations, tighter schedule integrity, larger network. For Middle East and Southeast Asia low-cost international, Air India Express is now genuinely competitive with IndiGo on price and beats IndiGo on baggage allowance (15 kg standard vs IndiGo's stricter international baggage policy). For loyalty earning, Air India Express ties into the Flying Returns / Star Alliance ecosystem; IndiGo is loyalty-free.
Two different histories merging
To understand the 2026 comparison you need the recent history. Air India Express in its previous form was the Air India subsidiary running 737-800 metal on Gulf routes — a low-cost product with mediocre service quality and a chronic on-time problem. In 2024-2025, Air India Express absorbed AIX Connect (the rebranded AirAsia India), which brought in A320 metal, a different operational DNA and a domestic short-haul network. The merged airline today is materially different from the old AI Express most Indian flyers remember.
IndiGo has been the gold standard of Indian aviation operationally for over a decade. Single-type fleet (A320 family), tight schedule integrity, the largest domestic network and a rapidly expanding international network. The 2026 question is no longer 'who is the best low-cost in India' — it is 'which one is right for which trip'.
Network and frequency
IndiGo's domestic network is unmatched. Around 75 to 80 Indian cities, multiple daily frequencies on every trunk route (Delhi-Mumbai 30+ daily, Delhi-Bengaluru 25+, Delhi-Hyderabad 18+ and so on), and the deepest Tier-2 connectivity via the ATR 72 fleet. International network includes Delhi to Dubai, Bengaluru to Singapore, Bangkok, Doha, Singapore, Kuala Lumpur, Jeddah, Riyadh, Bali, Phuket and an expanding map.
Air India Express's network post-merger covers roughly 35 to 40 Indian cities (smaller than IndiGo but covers all major Tier-1 and most Tier-2). International strength is the Gulf — strong daily frequencies to Dubai, Sharjah, Abu Dhabi, Muscat, Doha, Jeddah, Riyadh, Kuwait, Bahrain. Southeast Asia (Singapore, Bangkok, Kuala Lumpur) is now in the network. The Gulf network is genuinely competitive with IndiGo on frequency.
Baggage — Air India Express wins on international
For domestic, IndiGo and Air India Express both offer 15 kg checked baggage on standard fares, with 7 kg cabin. For international, the difference shows. Air India Express's standard international fare typically includes 15 kg checked, with higher allowances on some routes (25 kg on certain Gulf rotations for an Indian-origin booking). IndiGo's international standard fare includes 15 kg checked but the bundle structure means you often pay separately for the second bag and the on-board.
For NRI travel home with heavy bags, Air India Express's posted baggage allowance and the option of buying extra baggage at booking is typically more economical than IndiGo's add-on pricing. Always verify the specific fare class on the booking flow — both airlines have multiple fare bundles with different baggage included.

Seat and cabin
IndiGo cabins (A320neo, A321neo) are configured at 30 inches of standard pitch, 3-3 layout, with the XL, Extra Legroom and preferred upgrade options described in our IndiGo seat map guide. Air India Express A320 cabins are similarly configured — 30 inches standard, 3-3 layout. The seat hardware is broadly comparable.
The 737-800 cabins still in the Air India Express fleet (legacy AI Express metal) are 3-3 in a slightly different layout, with similar pitch. Air India Express has been migrating premium-economy-style seating (a small block of extra-legroom rows up front) into the merged fleet — these are sold as Express Plus and roughly compare to IndiGo's Extra Legroom rows in pricing and comfort.
On-time performance
IndiGo's on-time performance is the highest in the Indian market over a multi-year window — DGCA data consistently shows IndiGo OTP in the 80-85 percent range on a calendar-year basis. Air India Express's OTP improved meaningfully through 2024-2025 post-merger and now runs in the 70-78 percent range — better than the old AI Express, broadly competitive with SpiceJet and Akasa, but still a step behind IndiGo.
The honest read: if your itinerary involves a tight onward connection (you have under 90 minutes between flights at DEL or BOM), IndiGo's tighter schedule integrity is genuinely worth choosing over Air India Express. For point-to-point with a relaxed schedule, the gap matters less.
Loyalty and earning
This is the biggest single difference. IndiGo has no loyalty programme — you earn nothing for IndiGo flying. Air India Express flights earn Flying Returns points (the Air India loyalty currency) and Star Alliance partner-earning kicks in. For Indian flyers building tier status with Star Alliance, Air India Express becomes meaningful, particularly on Gulf rotations where the fare price is competitive with IndiGo.
If you do not care about loyalty — most domestic flyers do not — this is a non-factor and the comparison comes down to network, baggage and OTP. If you do care, Air India Express is the better long-term play.
Food, in-flight and customer service
IndiGo's BYOSnack model is buy-on-board only — packaged meals (sandwiches, pasta, biryani trays) at INR 200 to INR 350 a pop. Quality is consistent if uninspiring. Tea, coffee and water are sold separately. Air India Express on Gulf and Southeast Asia rotations now includes a complimentary hot snack and beverage on most international flights — biryani, sandwich, chai. On domestic, it is similar BoB to IndiGo.
For customer service when things go wrong (delay, cancellation, rebooking), IndiGo's process is more standardised — automated SMS and app rebooking, refund processing within posted SLAs. Air India Express has improved its customer-service infrastructure post-merger but is still behind IndiGo on consistency. SpiceJet, for context, is meaningfully behind both — see our SpiceJet 2026 reliability assessment.
When to book which
Book IndiGo for domestic short-haul where on-time matters, for routes that IndiGo serves with higher frequency and where you do not value loyalty earning. Book Air India Express for Gulf international (heavy baggage benefit), for Star Alliance loyalty earning, and for routes where the fare gap is meaningful.
