The most important part of flying comfortably is to pack correctly – you want to have one carry on bag, that is almost exclusively used for items you will/may need on the plane itself. I say almost exclusively because lost luggage does happen, and its good to have clothes for your first day with you, so that you can still go out before they get your bag returned. You’ll want the following items:
1. Paperwork – Passport, Visa, any other paperwork you need at any point in your flight shouldn’t ever leave your side. The same is true for your travel insurance paperwork, which could be needed at any point in your travels.
2. Cellphone – download the airline’s app, as well as a few shows on Netflix/other streaming service, and music/podcasts. You can’t always download these when in flight, and the airport’s WiFi is always a bit tricky. Bring charging cables with USB end, and an adapter for USB/North American (most airplanes have both outlets, but my experience has been that one is always out of order). Ideally you’d also bring a Brazilian/North American adapter, but those are expensive in Canada, and are better purchased in Brazil.
3. Cellphone Charging block – this is your backup in case both outlets are broken. Most I find can’t keep up with the battery drain from heavy use, but even so, it will significantly extend your battery.
4. Cell phone stand – a lot of airlines have gone to providing in-flight entertainment through personal cellphones. It makes sense, because they don’t have to pay to maintain the hardware, but it can be uncomfortable for long flights. You want a dedicated cellphone stand, that raises your phone up slightly – this way you don’t have to have your neck bent down at an extreme angle for the whole flight. You don’t want it too high, as that risks the phone falling and breaking, but a small distance makes a world of difference.
4a. Laptop – personally I find that a laptop is a bit cumbersome on the plane, and I actually prefer to watch shows on my cellphone with the stand, because the seats put you so close to the laptop, but to each their own.
5. Headphones – ideally, you’ll have two sets. One earbud style, which is useful for those airlines that only allow this style during takeoff and landing. The other ones you want are Active Noise Cancelling, Over-Ear style. These can be found for less than $100 on Amazon, and are well worth the money. Its a risky purchase online, because youtube videos don’t do them justice, but the trick is to search for 3 star reviews where the complaint isn’t something that bothers you. You don’t need the expensive ones that cancel out all noise, as long as the low-beat of the airplane engines is drowned out, you’ll be able to actually enjoy in-flight entertainment, and sleep much better. These have completely revolutionized flying for me.
6. Candy – If you have trouble sleeping on the flight, a big sugar rush right after the in-flight meal will lead to a sugar crash and may help you nod off to sleep. Having a beer before/on the flight helps with this too.
7. Cash/Card – not everywhere will take card, and not everywhere will take cash – bring both, so you can buy something if you need.
8. Gum – if you have problems with the takeoff and landing, gum can help, although I prefer to just hold my nose and swallow to equalize pressure to avoid the headaches.
9. Medicines – if you need to take them, obviously bring them with you.
10. Wet Wipes – everything is dirty on a plane, and you don’t want to get sick.
You don’t want to bring much more than this with you on the flight, because if the flight is packed, you might have to put your bag under the seat in front of you, and a full bag will take away the precious little leg space you have. Additionally, you’ll want space in your bag for Duty Free purchases.
