This is brilliant! Your genius knows no bounds. Next time a family of 4: parents and a 3yr 6 month boy and a 4 month old girl fly, I’m going to use your brilliance and suggest the following. 2 years is till when you get a free ticket. The sum total of their ages is under 4 years, so they are eligible for 2 free tickets. They just have to transfer some of the excess age from the boy to the girl. I mean if you can do it for baggage weights why not for age? Amirite?
If I take a flight and the baggage limit is 15 kg, if I carry 16 kg then I'll pay only for the extra 1 kg, not for the full 16 kg.
But on Swiggy, I ordered lassi from 7.3 km away. I have a Swiggy One subscription where delivery is free up to 7 km.
Instead of charging for the extra 300 meters, they charged me for the full 7.3 km. Makes no sense.
