Spouse and I planning our first ever trip to Europe. We are treating our adult children and their spouses as well. I thought it would be for nice for spouse and I to fly business class, since we have never had a huge splurge of a vacation, the flight is long, and we fly overnight. The difference in cost is $4K per ticket, so a total of $8K. Adult children and their spouses will fly coach. We have plenty of money; that isn't the issue. Spouse just feels that $8K is silly to spend when we can just fly premium economy, and he feels it's wasteful. We agreed to ask the jury and will abide by your decision!
