"Consider taking a flight bump if flexible; there are often financial incentives and potential upgrades. If an extra night stay is required, airlines provide hotel accommodation. This sometimes results in direct flights, reducing overall travel time."
When flying coach, select aisle and window seats, leaving the mid seat empty. It's likely others won't pick it. If the flight isn't full, you'll get a row together. If someone takes the mid seat, ask to switch so you sit together. No one prefers a middle seat.
"Tip for traveling abroad without cellular data: Ensure Google Maps is fully loaded when you have wifi. Don't quit the app, and GPS can be used without data. Preloaded maps will show details like street names."
"AirBnB is cheaper than hotels and you meet intriguing people. It's like upscale couch surfing. I've traveled continents using AirBnB without any issues; it offers unique experiences unavailable in hotels."
