I tell locals I can "speak, read, and type", but only have 1st grade writing abilities in Mandarin. The key is typing -- you can chat on Line, WeChat, email, or any mobile apps to accomplish day-to-day tasks. But the typing is phoenetic either via Roman pinyin, zhuyin, romaji, etc.
So yes, this problem only comes up in languages where drawing the characters are mostly independent of the pronunciation. You don't need to type individual words, you can type phrases and the input tool presents choices sorted by most commonly used. Therefore, even sending communication is closer to a reading exercise rather than a writing exercise.
Even though most domestric lounges are hit-or-miss, it's a way to trick myself into getting to the airport 30 to 45 minutes earlier than I would. That way, if I'm running late, worst case I miss the lounge or cut short the time.
For those complaining that lounges are overcrowded with mediocre food, it's true and getting worse. However, it's buffet style - select a healthy salad option with a reasonable protein. Non Priority Pass options are somewhat worthwhile -- United Clubs have gone through a massive upgrade post Covid and so far haven't been too crowded. They also allow access upon arrival, if you really need to fire off some emails and hydrate upon landing.
As for in-flight, for former gaming geeks, try classic emulators. They won't require internet and drain very minimal battery life on your latop.
The adjacent hack is to bring an empty water bottle in your carry-on, which you fill once you clear security. Then, you have a full bottle of water and can decline everything from the "beverage cart" on your flight, meaning you never need to worry about managing a precarious open cup of liquid and ice sitting on your in-flight tray.
