Medical transportation
If the patient's condition is not critical at this stage (ie does not require a medical attendant) it would be better and cheaper to purchase a business class or first class seat on an airline that have fully reclinable seats. O2 can be purchased from the airline, around $au150.00 a bottle or you can take your own as long as it is approved by the airline for use in their cabins. Medivac charters are very expensive compared to First or Business class airfares. Just a suggestion, I hope it helps.
