First flight since my hip replacement in two weeks. Will the titanium set off airport security, and what actually happens when it does?

The sleep saga crowd will remember me (right hip, end of April, back-sleeping misery, all resolved). New chapter: my daughter has booked us flights for the first week of July, a short hop for my sister's birthday, and she's more excited than I am, because I have developed a completely disproportionate dread of the security queue.

Not the flying. The SCANNER. Will the hip set it off? Do I get marched off somewhere while the whole queue watches and my daughter holds my shoes? Do I need a letter from the surgeon, or one of those implant cards people mention, and where do you even get one? Do I have to explain my hip to a stranger with a hundred people behind me? I've stood in that queue dozens of times in my life without a thought and now I'm rehearsing it like an exam.

Also slightly dreading the standing, if I'm honest, the hip still complains about long queues at week nine. It seems ridiculous to have been calmer about the operation itself than about a metal detector. Someone who's actually flown with their new hip, please tell me how this really goes.

Flew at five months for a cycling trip and plenty of times since, so here's the pattern I've observed. At the airports with the modern scanner, the pod where you stand with your hands over your head, I have sailed through more often than not, hip completely ignored. The one that beeps is the old-fashioned doorway arch, the classic metal detector, usually at smaller airports.

And when it beeps, here is the entire drama: I say "hip replacement, left side", an officer waves a hand wand over that hip, gives it a quick pat, thanks me, done. Ninety seconds, most of which is me getting my belt back on, which frankly the hip finds harder than the scan. Nobody has ever asked me for proof, a letter, or a card. These days I say it BEFORE I walk through the arch, which seems to turn me from a mystery into a Tuesday.

Four flights in. The implant card that came with my paperwork has been examined by precisely nobody. Last officer just said "we get twenty of you a day" and waved the wand. The queue cares less than you do, Helen.

Helen, the reassuring summary first: yes, your hip may set something off, no, it is never a problem, and the whole encounter typically costs one to three minutes. But since the dread feeds on not knowing the mechanics, here are the mechanics.

There are two different machines, and they see your hip completely differently. The walk-through arch is a metal detector: an electromagnetic field that responds to conductive metal, and a hip replacement is a substantial piece of metal, the stem and ball are titanium alloy or cobalt-chromium and a full implant commonly amounts to a few hundred grams. So the arch can certainly alarm, though whether it actually does varies with the detector's sensitivity setting, which is why the same hip can beep at one airport and pass silently at the next, and why neighbours comparing notes conclude it's a lottery. The newer body scanner, pbike60's hands-over-head pod, uses millimetre waves that image the surface of the body and flag anomalies as a generic box on a cartoon outline; an implant seated deep inside the joint often passes it without comment, which is exactly the pattern he describes, and when the software does box the area you get a brief targeted check of that spot, not a full search. Neither machine shows anyone your hip, your scans, or anything resembling an X-ray. When an alarm does need resolving, it's as the others describe: say "I have a hip replacement" before you walk through, expect a hand wand or a pat-down of that area only, and know that you're entitled to ask for it seated, or in private, if standing or the audience bothers you. No letter or medical report is required at security.

On implant cards: worth carrying, but understand their real status. They are courtesy documents from the manufacturer or hospital, not security credentials, and officers cannot wave you through on the strength of one, because a card can't be verified at a checkpoint; the screening resolves the alarm regardless, as Trev's uninspected card proves. Where a card earns its keep is abroad with a language barrier, and at future medical appointments, so keep it in the bag rather than expecting it to part the queue. As for the hip itself at nine to eleven weeks: queue fatigue is entirely normal at that stage, an aisle seat and a walk along the cabin are sensible on any flight this early, and the airline's assistance service exists for exactly this recovery window, using it once is logistics, not surrender. The site's guide to daily life after a hip replacement covers the travel odds and ends around this. One deferral, since your clearance conversations were about sleeping rather than airports: if your team hasn't specifically mentioned flying, a quick call to confirm they're happy with the timing is worthwhile, especially if any leg of the journey is long haul. For a short hop at your stage, most teams will be delighted you're going.

I rehearsed a whole speech for my first trip, medical history, surgeon's name, the lot. The officer got as far as "hip" and tapped his own knee: "titanium, 2019". The queue is full of us, Helen, we just don't wear badges.

One practical thing nobody warns you about: wear slip-on shoes. The scanner was nothing, but bending to relace shoes in the tray scrum at three months post-op was the actual physical challenge of the day. The tray dance is the real screening.

Back, and reporting in full. Outbound: the modern pod, hands over head, walked straight through, nothing flagged, felt almost cheated after a fortnight of dread. Return leg, older terminal, the arch beeped, I said "hip replacement" like I'd been coached (I had, by this thread), hand wand, little pat, ninety seconds, and the officer told me about his mother's knee while he did it. The card never left my handbag.

Moira, the slip-on shoes advice was worth the whole thread. The genuinely hard part of the day was the walk to the furthest gate in the building, because it's always the furthest gate. The machine I feared most turned out to be the one that noticed me least. Sister's birthday: excellent. Hip: fine. Dread: retired.
