Get a Cosco Scenera. They're super cheap and light. Really good for travel. [https://www.canadiantire.ca/en/pdp/cosco-scenera-next-convertible-car-seat-boulder-0468824p.html](https://www.canadiantire.ca/en/pdp/cosco-scenera-next-convertible-car-seat-boulder-0468824p.html)
If you do go the car seat route, I highly recommend getting the Cosco Serena! It’s inexpensive, simple, and super light weight. Just make sure you adjust the height straps ahead of time. We have bulky every day car seats, and they never would have worked for travel. We just draped it over our stroller awning while going through the airport, but if you have a big undercarriage, it might fit there too. Not quite as long, but we did a 5.5 hour flight with our son at 20 months and he slept in it nicely for the late night flight.
We got the Cosco Serena for traveling. It doesn’t click into a stroller, *but* is still portable depending on your stroller. If you have a bigger one, it could definitely fit in the under carriage. Ours is compact (Thule spring) and it fits perfectly when it’s upside down over the sunshade. That’s how we bring it around the airport. Looks a little silly, but it works. So maybe not ideal to just have on hand at all times, but if you know you’ll likely need it, it’s light and portable enough that you could probably bring it. They also make car seat back packs. It’s super light, so would be a little bulky but not too heavy to carry that way.
1) delta and suncountry are my only experiences. Seemed like the same old stuff. Both fine enough. Just pay attention to carryon restrictions but I believe diaper bag doesn’t count as a carryon. 2) we brought our own guava lotus and gate checked it 3) depends on your options. The extra leg room seats are always already booked or crazy expensive so not worth it for us. We aren’t tall people so it’s less horrible. 4) check bags is way easier IMO and check the car seat (but get a cheap and light travel one -Cosco Serena for 60$ Walmart so you don’t care if it’s lost or damaged). 5) watch some YouTube videos for advice. Ppl have done this hundreds of times and made good content. Baby wear.
There are great low cost, light options like Cosco Serena that are good for young kids and for older kids a small packable booster like mifold or an inflatable booster
You will not find a toddler seat that goes stroller to car. Cosco Serena is going to be the lightest and smallest option, but it Maxs out quickly. I love our Britax poplars. They’re about 23lbs and compact so should fit most if not all cars and super easy to install. They have higher limits. You’d probably want a wagon/cart or a stroller with a big under space for it. I think it would fit under my stroller but I haven’t looked at all. Another option would be to look at Diono. I hate ours as it’s very long, but if you can center install/are short yourself it might be better? The seat folds on ours and you can get backpack straps for it! It’s heavier though, about 35lbs.
We travel with the cosco Serena but our kid is 1.5 years old so younger than yours. It fits under our stroller (Uppababy Cruz) which we gate check and then we carry and install the car seat. Easy install in cars and taxis too using seatbelt. I think they make bigger ones for bigger kids. You can get a backpack or bungee cord it to luggage for easier transport.
We have the Scenera Next and love it. Check the height limits, though. It's very lightweight. The trolley didn't work for us, so we just strapped it onto baby's carryon suitcase and it worked well for us. It's very affordable, too.
Every car seat sold in Canada is certified to be used on airplanes. I’m currently on an ACR flight and they just looked for the Canada sticker. Definitely get a travel car seat if you can afford it. (Cosco Serena next, or Evenflo sonus are both light and fit in the seats well (even with fixed armrests). If you have any questions please reach out. It’s so intimidating flying with a car seat and infant for the first time. I hope everything goes okay.
My kids LOVED the Cosco Serena for travel. They sure seemed to be comfortable. They grew out of it height wise much quicker than their standard seats though. If the kid isn't going to fit well in an airplane buckle (like under 3?) I'd buy one for a long flight. We found it so good to have on overseas flights because the kids could sleep well, without a parent having to hold them, and they also couldn't unbuckle themselves easily like an airplane buckle allows.
It is safer for them to be in a car seat in case of turbulence or other emergencies. We also find that it helps our very busy toddler stay still for the flight. We use [Cosco Scenera Next](https://www.walmart.com/ip/Cosco-Kids-Scenera-NEXT-Convertible-Car-Seat-Cobblestone-Infant-Toddler-Unisex/534841958) and a car seat dolly from Amazon to transport it in the airport.
