- **Tier 1** (Should Book These):
Vistara (for comfort, feels, food)
Indigo (for being cost effective, on time, no frills)
- **Tier 2** (Doable):
Air India (some planes are good now, but still inconsistent)
Spicejet (if you are in luck, it's not too bad anymore)
- **Tier 3** (I Don't Value My Life)
Air India Express (fka Air Asia - avoid for life)
Akasa (it's a great flight, as long as you assume your takeoff is at T+2 hours by default)
Feel free to opine but this is how it is. I fly every month and have done so for years now.
Hope this helps before you book for Diwali.
