A new TSA pilot is quietly bringing back the days of greeting loved ones at the gate. At a handful of US airports, travellers with TSA Pre-Check (including Global Entry members) can now clear security without holding a boarding pass, as long as they register in advance. One writer put it to the test at Los Angeles International, taking his young son through security to surprise his wife after a week away — and the verdict is encouraging, with a few caveats worth knowing before you try it yourself.

The logistics are simple. You apply online one to three days before your visit, logging in (or creating an account) and entering the date, the airport, your Known Traveller Number, full name and date of birth. Anyone accompanying you needs to be listed too — adults generally need their own KTN, but for the writer's son, a birthday was enough. Approval isn't instant: you submit, then check the online dashboard the following day for confirmation. He applied on September 18, roughly ten days after the programme went live, and the approval was waiting for him the next morning.

At LAX, the family used the Pre-Check lane, where the agent knew of the programme but had never actually seen it in action. The author's tip here is the most valuable part of the whole exercise: don't just show the confirmation number. Open the confirmation itself and click through so the screen displays the names of everyone on the reservation. The initial agent couldn't work out how to clear the child, and it took a supervisor a few minutes to sort out — but once both names were visible, everyone walked through without fuss.

Then came the payoff: greeting his wife right at the gate, no arrivals-hall scramble required. Anyone who has tried a curb-side pickup at LAX on a Friday night knows the chaos — circling the loop, coordinating by text while bags trickle out. Meeting airside cost more than a quick drive-by, he notes, but it was far easier on the nerves. The programme's real sweet spot is probably the scenarios raised when the scheme was first reported: greeting an arriving relative, or escorting someone who genuinely needs help getting to the gate, like elderly parents or a nervous first-time flyer.

A few practical pointers if you're tempted. Sign up at least a couple of days ahead — same-day applications don't work, and the programme is still new enough that frontline staff may need a nudge. Save your TSA login on your phone before you leave home, because you'll need to pull up the dashboard at the checkpoint: log in, tap the three-line menu at the top right, and select dashboard. Bring your ID as usual, expect a face scan, and be patient if the agent needs to call someone over. Given that the programme had been running less than two weeks when this trip happened, the kinks will likely smooth out as more officers encounter it.

Is it worth it just to visit an airport lounge without flying? Probably not. But as a way to meet someone you love at their gate — or make sure a parent gets safely onto a plane — this is a genuinely welcome bit of common sense from the TSA.
