I bought the tickets. It wasn't $8,000, but it was close. The shock and horror of spending that much was mitigated substantially by the discovery that it was BY FAR the best price. I found something fifty dollars less on Delta, with yucky transfers in NY, and other than that we were talking at least $2,000 per ticket. Yup yup. And at least this way we are going BA, which is one of my favorite carriers. Much better than, say, Lot. Or Tarom. Or Air Ghana.
Now to find an apartment. And get a passport for Avtalyon.
