Extreme distance flights such as those lasting over 15 hours are perhaps the most testing experiences for air travelers. Some tips that may help travelers cope with these flights include immersing yourself into in-flight entertainment and music, upgrading to a better class if possible, bringing along comfort gear such as noise-cancelling headphones and neck-pillows, boarding after resting and trying your sleep-aids beforehand.
Other useful tips include selecting a good seat using seat analysis services such as Seatguru and keeping yourself hydrated during the flight.
