Should I pay for a seat for my under-2 child?

If you can afford it, yes. Having their own seat allows you to bring a car seat, which is safer and makes it significantly easier for them to sleep.

Do I really need a car seat for the plane?

It is not required by law, but it provides a familiar environment for the child and helps them stay seated during turbulence.

Booking Flights to Europe with Kids

Book direct overnight flights to minimize layovers and prioritize booking a bulkhead or bassinet seat at the time of purchase. Use tools like Google Flights to monitor price trends for 3-4 months out, and always book directly through the airline's website to ensure easier seat assignments and rebooking support.

Choose your flight path. Filter for 'Nonstop' flights only. A 9-hour direct flight is significantly easier than a 14-hour trip with a 3-hour layover, as you avoid the stress of terminal transfers and security lines with children.
Select the right time of day. Look for overnight departures. The goal is to maximize sleep; children are more likely to settle down if the flight timing aligns with their natural bedtime.
Secure specific seats. Call the airline immediately after booking to request a bassinet seat if your child is under 20-25 pounds. If you have older kids, pay the extra fee for 'main cabin extra' or similar seats that offer an additional 3-4 inches of legroom.
Verify baggage allowances. Check the airline policy for strollers and car seats. Most major carriers allow you to gate-check one stroller and one car seat for free, but verify if they need to be collapsed into a specific size bag for the gate.
