Travel is constant weighing of savings vs. convenience. When you travel with kids the equation gets more complicated. When is paying more to make travel less stressful really worth it? The airport VIP services that airports, airlines, credit card companies and private firms are offering these days raised this question for me. These for-fee perks start at around $50 and go beyond $1,000 per person.  I think that at the low end they’re worth the splurge if you are flying solo with a child, flying with multiple small kids, or traveling with both older grandparents and children.
