Free travel calculators: flight time estimator, hotel cost comparison, currency conversion, packing weight, and international trip budget.
Trip budgeting, flight and driving times, currency, jet lag and the small costs that add up between booking and coming home. 48 calculators.
Jet lag recovery is built around the asymmetry most advice skips. Flying west is easier than flying east, and not by a little. The human circadian day runs slightly longer than 24 hours, so stretching it westward is working with the body and compressing it eastward is working against it. The usual figures are about one day of recovery per time zone going east and roughly two thirds of that going west. London to New York and back are not the same trip.
Flight carbon uses distance bands rather than a flat per-kilometre figure, because short flights are far worse per kilometre than long ones. Takeoff and climb burn a disproportionate share of the fuel, so a 400 km hop can emit more per passenger-kilometre than a transatlantic leg. Two short flights are not equivalent to one long one of the same total distance.
Currency pages ask for the rate rather than fetching one. The site is static with no server, so a live rate would be a lie about freshness. Type the rate your bank actually gave you and the result reflects what happened, including the spread, which is usually the part being hidden.
