I'm going to Japan in 2 months, for 2 weeks, to see my wife's parents in Japan. (I live in Los Angeles.) They are getting up in years and their health is declining so this will probably be the last time we see her dad, and maybe her mom too. The trip will cost $6,000 minimum for the 3 of us to go. My father lives in Texas, and we went this spring. That cost $2,000. Next summer, we may go to France for a couple of weeks to see my mom and a bunch of other relatives. That will cost another $6,000, at least. So, at a minimum, we'll spend at least $14,000 in the space of 15 months to see relatives. Can't do that every year, or even every other year and hope to fund our retirement and my son's college fund.
I do, and domestic flights for 3 people cost that much, and that includes the car rental, gas, parking, baggage fees. Luckily I did not have to pay for a motel, and dining out three times a day or the trip to Texas would have cost more than $3K.
