I'm planning for travels with a 22mth old and am facing a dilemma on whether to let him sit in the bassinet or get a seat. Any advice?

How long is the flight? We usually book without a seat but will request to sit in a row with an empty seat at the check-in counter. They are usually very kind with parents so should not be a problem unless it's a full flight. If it's a long haul flight and you've booked a rented car to be picked up the airport, I would suggest to bring a car seat that complies to the airline requirement. I find that it's more convenient as the toddler can sleep without disruption as compared to having to remove the toddler from the bassinet each time there's turbulence.
