To begin - never, EVER listen to what media says. They make a mountain out of a tiny stone.
Birdstrikes do happen. But so do deerstrikes when you drive. Has that happened to you? Me neither. So don't worry about that. And even if it happens, a plane can still fly with the remaining engines.
You can bring as many bags as you want on your trip. But there's a weight limit, though. Take a look at your ticket, and you'll see how much weight you can bring. It's normally between 40-60 lbs. But it depends on the airline and plane. Remember, though, to pack less than the maximum allowed limit. In some strange way, the bags are always heavier when you go home...maybe because of all the stuff you have bought over there. You can only bring one bag in the cabin, and it's max 10 lbs...well, that's what we have over here at least.
Ask the cabin crew if you can visit the flight deck. They'll probably let you once you're airborne. Tell them that you are a little scared of flying, that can help.
You can bring your video camera, as long as it is turned off during take-off and landing.
Is your flight a non-smoking flight? If not, tell the desk clerk at the airport that you want a smoker-seat. If it is a non-smoking flight...well, you'll just have to put.
Jet lag might turn you upside-down. Your body will say that it's time to sleep, when it's noon over there. It passes in a couple of days. Try to get some sleep on the plane.
Ireland has lots of beer!
No, what I know is that they have good beer and nice people (most of them). The country-side seems nice too...it all depends on what you want to do.
Don't worry, be happy.
