The original CTA: 'Book Now'. Standard. Functional. Ubiquitous.
The hypothesis: 'Book Now' is a command. It asks users to do something for the product. 'Secure Your Seat' is a benefit frame. It tells users what they get — specifically, the security of knowing their seat is reserved.
The psychology: loss aversion + ownership language. 'Secure' activates the fear of not having something locked in. 'Your Seat' creates psychological ownership before purchase.
We ran a 4-week A/B test across mobile booking flow. The result: 8% increase in tap-through to payment. On IndiGo's booking volume, that's material.
The lesson isn't 'use these exact words'. The lesson is: every CTA label is a micro-copywriting decision that encodes a psychological frame. 'Book Now' is anxiety-neutral. 'Secure Your Seat' is anxiety-resolving.
CTA copy is product design. Run it through the loss aversion lens: does your button tell users what they get, or what you want them to do?
