  "what": "Two dates are bought at once, weeks before any operation happens. The outbound follows the clinic's calendar. The return is fixed against an expected recovery that nobody has yet examined, and it is the date that collides with clinical reality later.",
  "story": "Published guidance on how long to wait before flying is written by aviation medicine, not by the clinics that sell packages, and it is specific by procedure. The UK Civil Aviation Authority states that \"travel should be avoided for 10 days following abdominal surgery\", that \"it is advisable to avoid flying for approximately 24 hours after laparoscopic intervention, due to the residual CO2 gas\", and that after neurosurgery it is \"advisable to avoid air travel for approximately 7 days following this type of procedure\". For intra-ocular procedures it gives \"1 week should elapse before flying\", extending to \"approximately 2 weeks if sulphur hexafluoride is used and 6 weeks with the use of perfluoropropane\" where gas is injected. For plaster casts it notes that \"the majority of airlines restrict flying for 24 hours on flights of less than 2 hours or 48 hours for longer flights\".\n\nThe CDC Yellow Book carries a blunter version: travellers \"should not fly for 10 days after chest or abdominal surgery\", and it puts 7 to 10 days on laser and cosmetic procedures to the face, eyelids or nose. The NHS gives 5 to 7 days after breast surgery and liposuction and 7 to 10 days after facial procedures or an abdominoplasty, and names the reason: \"Air travel and major surgery increase your risk of a blood clot, which can be life threatening.\"\n\n*Inference —* those intervals are longer than the ward stays most packages name, which is how a return ticket bought at booking ends up landing inside the window the guidance describes.",
  "how": "*Trade practice —* a cheap fare is the one with the change fee, and the fare rules that make a ticket cheap are the rules that make a slipped discharge expensive. Airlines may also require medical clearance for a passenger travelling soon after surgery, and the clearance decision belongs to the airline's medical department rather than to the treating surgeon.\n\nWhat a reader would have to ask: what a date change costs on the fare bought, whether the airline requires a fitness-to-fly form and who signs it, whether the seat can be changed if a cast or a drain makes the booked one impossible, and who pays for the extra hotel nights if the return moves.",
  "today": "As of 16 September 2026 the aviation guidance and the package length of stay are published by different parties with no obligation to agree, and no provider this project read prices the gap between them."

 "metrics": {
  "days_before_flying": 10,
  "note": "Ten days is the CDC Yellow Book interval after chest or abdominal surgery and the UK Civil Aviation Authority interval after abdominal surgery. It is not a universal figure: the CAA gives about 24 hours after laparoscopic surgery, about 7 days after neurosurgery, 1 to 6 weeks after intra-ocular procedures depending on the gas used, and airlines set their own restrictions on top.",
