Frequently Asked Questions
How do I estimate flight time between cities?
The flight time calculator estimates travel time based on the great-circle distance between two airports plus typical taxi, takeoff, and landing time. It accounts for average cruising speed of commercial aircraft (around 550 mph). Actual times vary with wind patterns, routing, and airline — use this as a planning estimate.
How long does it take to recover from jet lag?
A general rule is one day of recovery per time zone crossed. The jet lag calculator factors in your departure and arrival zones, travel direction (eastward is harder), and gives personalized tips for light exposure and sleep timing. Flying east across 6 zones may need a week to fully adjust, while westward travel is typically easier.
How do I convert shoe sizes between countries?
Shoe sizing varies significantly between US, UK, EU, and Asian systems. The shoe size converter translates your size across these standards for men, women, and children. For example, a US men's 10 is roughly a UK 9.5 and EU 43. Always check brand-specific charts as sizing can vary between manufacturers.
How do I budget for international travel?
The travel budget calculator helps you estimate daily costs for accommodation, food, transportation, activities, and miscellaneous expenses in your destination. Combined with the currency converter, you can see exact costs in your home currency. Budget travelers can expect $30-80 per day in Southeast Asia versus $100-250 in Western Europe.
