Re: in a 3-3 economy class configuration.
Last job had a lot of international travel. I do not miss it.
The table is useful if you don't have one of those huge "laptops" (luggables, I'd say, or your lap is bigger than mine). I bought an eleven inch Lenovo, low power, ten hours on battery, small enough to work on a plane (if I did not booze myself up in the lounge to numb the pain of air travel and slept most of the flight - a viable plan). Having a high-ish frequent flyer status made some things less aggravating, but since I traveled a lot (too much) the sum of annoyance was high enough to make me not want to go on holidays anywhere I need to fly. Admittedly, one gets used to all sorts of things and is pretty unfazed by most curveballs airtravel throws you. Winter storm, flight cancelled? Ah, I'll spend a night at some hotel, maybe can explore the snowy city. Flight delayed, missed connection? Lounge, have lunch / breakfast / dinner, drink a nice glass of wine (depends on the airline), they'll get me on the next plane. Luggage lost? I got most things with me, it'll turn up eventually, yeah, I'll take the "socks, undies, shirt" money and get changed. Just... relax. Especially when talking to ground staff, who are really not at fault for any of these things. Have a friendly word for them, the job is stressful enough. Show patience. And just... relax. Ask them for a voucher to enter the lounge, some actually can give these out (if you are not eligible) but only if there's not a massive mob of angry paxes that would then shout "UH ME WANT THAT TOO!"
