Air India Express (IX), the low-cost arm of Air India (AI), is steadily scaling up its operations amid a growing fleet and strengthened metro city hubs. While the airline is reinforcing its presence at key metros such as Hyderabad (HYD) and Bengaluru (BLR), its penetration into Tier-2 and Tier-3 markets remains modest by comparison.
A recent schedule analysis by aviation expert Ravreet Singh, covering the week of August 11–18, 2025, reveals Air India Express operating 42 non-metro routes across 21 city pairs using its Boeing 737 and Airbus A320 aircraft. The airline conducted roughly 302 weekly departures, offering approximately 55,000 seats. Despite this growth, IX’s footprint in smaller markets remains limited, especially when measured against low-cost carrier IndiGo (6E).
The disparity is considerable: IndiGo operated nearly four times more non-metro routes during mid-July 2025, scheduling 157 routes over 78 city-pairs, and running in excess of 1,000 weekly departures with over 212,000 seats available. Both airlines serve similar average route lengths — around 768 km for IX and 893 km for IndiGo — with comparable block times of about 1 hour 39 minutes.
Air India Express’s non-metro service frequency tends toward minimal daily flights. Only one city pair exceeded 14 weekly departures, two routes operated 8 to 13 times weekly, and the majority offered a steady but limited seven departures per week. Four routes fell below daily frequency altogether.
IX’s strategy in non-metro markets is influenced by regulatory obligations. Over half of its 21 city pairs fall under CAT-II/IIA route obligations, which are designed to maintain connectivity to smaller cities. In fact, IX often enjoys monopoly status on 11 of these routes, giving it a unique presence in certain regional markets.
Guwahati (GAU) stands out among non-metro hubs, with six routes and 54 weekly departures, followed by Pune (PNQ) with four routes and 29 weekly flights, and Bhubaneswar (BBI) offering five routes and 28 weekly services. By contrast, Air India’s full-service carrier plays a smaller role in this segment, servicing just eight routes with limited frequency and a focus on compliance rather than expansion.
Within the broader Air India Group strategy, full-service Air India consolidates its growth at Delhi (DEL) and Mumbai (BOM), emphasizing a hub-and-spoke model aimed at boosting international connectivity. Meanwhile, Air India Express positions Hyderabad and Bengaluru as important secondary hubs, particularly connecting South India with the rest of the country.
The challenge remains that Air India Group’s footprint in Tier-2 and Tier-3 markets is modest compared to IndiGo’s expansive non-metro operations. Even IndiGo faces tempered demand, with nearly 38% of its non-metro routes operating less than daily.
Looking ahead, the industry will watch whether Air India Express commits to deeper expansion into smaller domestic markets or continues to consolidate its focus on metro-centric hubs — potentially ceding the rapidly evolving non-metro segment to IndiGo’s dominance.
