If you have any mobility issues be sure to contact your airline well before your departure time to find out what services and seating arrangements they can offer you. Try asking for an aisle seat as it will make it easier for you to move around the aircraft.
The low humidity on planes can be dehydrating. Drink plenty of water on your flight to stay hydrated. Avoid alcohol and caffeine, as these can dehydrate you faster. Use moisturiser to prevent your hands from drying out.
Deep Vein Thrombosis (DVT) commonly effects the eldery and those with heart disease or circulatory problems. Sitting still for long periods of time (such as on a plane) can increase these DVT risk factors. Do arm, leg and foot stretching exercises when you are seated. When possible, get up and walk up and down the aisles. Wear compression stockings to increase blood flow in your lower legs.
Mindful of medications
Pack a week’s supply of your regular medications in your carry-on luggage. This way, if your luggage is lost or delayed you won’t have any concern over taking your medication as required.
If you require oxygen or use of respiratory equipment such as a CPAP machine, contact your airline at least 72 hours before you fly so they can make arrangements.
