If you do not have need for excessive oxygen in your treatment I mean you feel good no dyspnea in rest do not worry about the flight. What about the AF. I would recommend you for safe reasons to do an EKG and to consult a cardiologist before the flight. May be in your condition the heart specialist might add something else in your treatment or increase the doses of bisoprolol. So good flightThank you Chat Doctor.  </s>
