11 Key Differences Between IndiGo, SpiceJet, and Vistara

7. Cabin classes and in-flight service options

Cabin variety is one clear dividing line. Vistara offers Business, Premium Economy and Economy classes, giving passengers genuine upgrade options and a premium economy product that sits between standard economy and business. IndiGo historically focused on economy but has introduced certain premium offerings and select business-class-style options on some routes; the carrier generally stays closer to low-cost economics. SpiceJet provides economy and limited premium seating options on select aircraft, but customer reports show variability in how consistent those premium touches are. In-flight service also differs: Vistara emphasizes a full-service experience with higher-quality meals and cabin service standards on premium fares, while IndiGo aims for efficient, no-frills service and predictable basics. SpiceJet’s experience can vary more by route and aircraft. If your trip from North America includes long domestic sectors or overnight travel, the presence of Premium Economy or Business matters a lot for rest and productivity; Vistara clearly targets that traveller. For short hops, the efficiency and cost-savings of a no-frills approach may be more attractive.
