Twenty-four hours before departure, compare the actual itinerary with the file. Has the last dive changed? Is the flight earlier? Did a symptom appear? Has a doctor added a restriction? Did the operator change the site or boat? A changed fact reopens the decision. Do not protect a holiday plan by quietly carrying an old answer into a new situation.
At the airport or transfer point, keep the dive computer, log, clearance note, insurance card and emergency contacts accessible. If you feel unwell, tell the airline or travel companion and seek medical help. Do not use a non-refundable ticket as a reason to suppress information. If you are symptom-free and within the appropriate interval, continue to observe your health. Do not assume the journey is risk-free.
Before the return dive, give the instructor the relevant medical and dive history. Confirm the site, depth, gas, supervision, equipment and exit plan. A gradual, familiar plan may be more sensible than immediately repeating the most demanding profile. If a physician has specified limits, ask the instructor to repeat them back so the whole team understands them.
