For any long flight, try to board really tired, which will let you sleep away many of the hours of boredom.
Wear a fleece pullover or jacket, since it tends to be cold in flight and you can always shed it if you get too warm.
The supplied tiny blankets and pillows are not enough and there may not be enough to go around anyway.
Bring a really engaging if not necessarily uplifting book and read it when you are awake.
Bring your laptop if you're going to anyway.
A few DVDs and you'll be set.
You can sometimes see interesting things out the windows, like other airliners going the other way as well as surface ships.
You will not observe airliners flying westbound during the times you'll be eastbound, but you can sometimes see the lights of surface ships if it's clear.
You will be flying eastbound at night.
A long flight is not all that much fun itself, but there is no other way to cross the Atlantic, unless you get passenger accomodation on a freighter (you can) or you cross on a cruise ship on its way to Europe for the summer, or on its way back to a Florida port or San Juan for the winter.
A cruise ship being repositioned is a pretty cheap and luxurious way to travel, but takes days rather than hours.
If I had the time, I'd take days in a cruise ship over hours in an airliner any day of the week, but most of us not yet in retirement can't spare that kind of time just for the journey.
Be happy to know that a flight acros the Pacific is much longer than your Atlantic crossing will be.
