How much should I tip when I travel?
This is TPG's practical breakdown of tipping norms across travel contexts—hotels, tours, cruises, all-inclusives, and flights—rather than a single-country etiquette guide. Key takeaways worth remembering: housekeeping deserves $3-5/day, tour guides 10-20% of cost, flight attendants generally can't accept cash tips (Frontier being the exception), and cruise/all-inclusive gratuities are typically already baked into the bill via daily service charges. It also flags cultural variation, noting tipping is unwelcome in Japan and Australia but expected across much of Europe, the Middle East, and Latin America.
