I think people are far too concerned with airplane seating. Concerning boarding: The plane takes off at exactly the same time, whether you're the first or the last person entering it. And upon arriving, the people are way quicker leaving. It's maybe a difference of 3-10 minutes. This might matter if you're in a hurry or want to be the first person in the customs line. I like to stay relaxed when travelling.

The noises are everywhere. There might be a minor difference and it probably really depends on the airplane model. The slight vibrations, engine noises and air-con noises are audible from front to the back. At least that's my observation. Most annoying thing I had happen is a crying and vomiting 5-year-old in the row next to me. But I don't think there is much you can do about that. I've sat right over the wings and it's fine. And I think I've read those are better concerning safety, but you don't need to worry about safety too much.

Even if you lose your boarding pass you'll most likely be OK. You can contact the aervice desks and ask for a new one as long as you have ID with you.
I've even shown up to the gate right before entering the plane and told them straight up "Yeah, I have no idea where my boarding pass went". Then they just find your name in the list of checked in passangers and do it manually.

You'll be fine.

Screenshots are good in my experience but make sure your brightness is fully maxed so they can scan it.

Which country are you flying from?

Experience in the EU:

• they scan the code
• quality of the pdf should be enough, make sure that brightness is high enough when you scan
• for the seats and check-in, that's airline dependent

Middle seats are usually "bad seats" as you are stuck between two people

QR on your phone is fine, but yes they do scan it. When they do, set your phone brightness to maximum.

I only care about front rows if I need to make a tight connecting flight, or if I fly to a country where I need to go through customs and it's a typical tourist flight, say to Thailand where every person leaving the flight before me means +3 min longer waiting in the queue.

Middle seats are my least favorite. Can't properly lean onto either side without feeling like you're creeping up on someone. I usually book aisle seats so I don't need to climb over someone on the way to the bathroom, but that's less of an issue on shorter flights. Window seats are better if you're planning to sleep.

Not quite sure what you mean though with physically check in to get a window seat. Whether I select it online or through the website generally makes no difference.

You'll be fine as long as you're giving yourself enough time before boarding to get to the airport. Just follow the airline's advice for how early to go. Once you have more experience flying, you may be able to cut that time down if you're familiar with the ebbs and flows of your airport.

QR code should be no issues. Turning your brightness up can help if it is being difficult to scan. If you still have doubts, get your boarding pass printed at the kiosk.

It may be more noisy near the engines but over the wings are the structurally safest parts of the plane.

Enjoy your trip!

Qr codes are usually very error tolerant by design. On the super tolerant ones they can work with like 30% of the code missing.
