output: hello thanks for writing your query to me I can understand your concern about your father I have seen all the reports attached herewith considering his general condition now your concern of air travel is very important to analyze before you book tickets with the airlines also it is not as simple as we think but with careful evaluation and guidance he maybe able to fly shorter destination flights very important to remember that he is still recovering from bad respiratory failure and cardiac event also still he is oxygen dependent at room temperature being hypertensive and recently hospitalized it is advisable to avoid any travel at least for weeks to prevent further complications fitness to fly for cold patients need to comply a definitive pre travel eligibility criteria and need necessary documentation from treating pulmonologist during air travel in commercial flights oxygen level falls considerably due to low cabin air pressure and we must supplement oxygen to prevent further hypoxemia and other complications so it is advisable to keep checking oxygen saturation frequently if the resting oxygen saturation is less than 92 he may require supplemental oxygen in flight but commercial flights generally dont allow to carry our oxygen cylinder but you can carry oxygen concentrator with prior confirmation from airline can provide supplemental oxygen if required during flight but it will be very costly and has to be booked well before in advance while booking tickets so it is very important to take opinion of his treating pulmonologist and do pre flight evaluation if he is fit to fly or not necessary medicines inhalers and tablets need to be refilled before flying once he is fit to fly while booking seats consider seat neat toilet to avoid walking frequently check oxygen saturation and avoid tea coffee or any other drinks during air travel please make firm confirmation for all the concerns with the airlines before you book tickets do not forget to get fitness certificate and medical prescriptions from your doctor and carry them during air travel uncontrolled moderate to severe cold pre flight fitness evaluation hypoxic challenge test if available locally oxygen supplementation either by cylinder or oxygen concentrator
