If you are a diabetic, consult your doctor about the drugs you need to take with you onboard. You can book diabetic meals at least 24 hours before flight departure through Air China’s hotline 95583. If you request special meals in addition to diabetic meals due to health or other special reasons, you should provide an accurate, detailed and clear description of the meals you need, so that our service agent can provide accurate information to our catering supplier to make sure that the meals you truly need can be provided to you onboard.
If you fly westward crossing multiple time zones, days become longer. So you should bring more medicines.
