Trinity Airways (formerly T'way Air) Lost Item: How to Search, and Why Delivery Won't Work From Abroad

Trinity Airways (formerly T'way Air) has run an online lost-item centre for longer than most Korean low-cost carriers. You can search for your item and request courier delivery from their website, which makes the process simpler than at several other airlines.

The catch is in the conditions. Delivery only goes to addresses inside Korea, electronics and valuables may be excluded from it entirely, and the items travellers most often lose — passports, ID cards, wallets with cash — are not held by the airline at all.

This guide covers how to search, what the conditions actually are, and what's left once you've flown home.

1. Searching for your item

Use Trinity Airways' lost item centre.

You'll need:

(1) Your booking — the search screen requires your lost-item report to match a flight you were actually booked on (2) Seat number — required when you submit a request (3) Where you lost it, and a description — for electronics, include the serial number if you have it

Note: Only items found on the aircraft appear here. Anything lost in the airport itself is handled by that airport's lost-and-found office.

Cabin items are usually recovered at the arrival airport, so search against where your flight landed rather than where it took off.

2. Two collection methods

When you submit a request you choose between collecting in person and courier delivery.

Trinity Airways' official guidance states that collection in person is the rule:

As a principle, lost items are collected in person by the customer, to ensure they reach the right person.

Courier delivery is the conditional exception, not the default.

3. The four conditions on delivery

Trinity Airways' official guidance sets these out directly:

However, courier delivery on a cash-on-delivery basis is possible only for items held at a domestic branch and only when domestic delivery is requested. The company does not accept responsibility for loss or damage occurring during delivery. In addition, delivery may not be possible for certain items such as electronics and valuables.

(1) The item must be held at a branch inside Korea

If your flight landed outside Korea, the item stays at that country's branch.

(2) Delivery must be to a Korean address

They will not ship internationally. Once you've left the country, courier delivery is no longer an option for you at any price.

(3) Electronics and valuables may be excluded

This is the constraint that catches most people. What travellers actually leave on aircraft is phones, earbuds, tablets, wallets, cameras — precisely the categories that may fall outside what will be shipped.

(4) Cash on delivery, with no liability for loss or damage

The fee is paid on receipt, and the airline does not accept responsibility if something goes wrong in transit.

4. Passports, ID and cash are not held by the airline

This surprises most people. Trinity Airways' official guidance states:

Important items containing personal information — such as passports, ID cards and cash — are handed over to the airport police. (This varies by airport.) Items exceeding duty-free allowances are handed over to customs.

So if you left a wallet on board and it contained your ID, it may not be with the airline at all. Searching the lost item centre will not find it, because it isn't there.

Two things follow from this. The handover practice varies by airport, so where your item ended up depends on where you landed. And if the item exceeds duty-free allowances, customs becomes involved, which adds another layer.

5. How long items are kept

Power banks are not stored at all because of fire risk — they're discarded as they arise. If you left one on board, it cannot be recovered.

General items are donated or discarded after 14 days.

6. Why none of this works once you've left Korea

If you're reading this from another country, walk through the options and you'll find all of them closed.

Courier delivery requires a Korean address. Condition (2) above is explicit. There is no international shipping option, and asking for one won't produce it.

Collection in person requires being in Korea. At the arrival airport's branch, during business hours.

The enquiry line is a Korean domestic number. 1688-8686, operating 07:00-19:00 Korea time.

If it's your passport or wallet, it's with the airport police. That's a separate process from the airline's, with its own identification requirements — and you can't walk into a Korean police office from abroad either.

And the clock is running. The 14-day window doesn't pause while you work out who to contact.

What's left is having someone in Korea collect it on your behalf.

If you lost it in the airport rather than on the aircraft

Items lost in airport facilities are handled by that airport's own lost-and-found office.

A "not found" answer is not final

Items do not stay put. A cabin item is often passed to the arrival airport's lost & found, or on to the police, rather than kept by the carrier. When Trinity Airways says it does not have your item, ask where it was transferred and on what date — not only whether it is there. Ask about timing too: an item handed in today may not be logged or searchable for several days.

If it has reached the police

If Trinity Airways does not have it, the item may have been handed to the arrival airport's lost & found or to the police, where it appears in Police Minwon24 (formerly LOST112) at minwon24.police.go.kr. How to search it is in the police lost & found guide.

Two things are true wherever the item came from. Nothing appears there for days after the handover, so an early search proves little and is not a reason to stop looking. And the record shows where the item was handed in — the office, depot or station that received it — not where you lost it, so keep the region wide and lead with item type and date.

If Korean is the barrier

1330 is Korea's tourist help line, run by the Korea Tourism Organization. It is free, answers 24 hours a day, and offers interpretation in English, Japanese, Chinese and other languages.

It is not a lost & found office — it holds no items and keeps no database. What it does is interpret, including on a three-way call with the Trinity Airways customer centre, an airport desk or a police station, and explain what a Korean-language page or notice actually says.

If the item is located but you cannot collect it in person — you have left Korea, or you are nowhere near the arrival city — Trinity Airways' own courier delivers only to Korean addresses, but the item can be released to someone acting for you with written authorization and their own ID, and that person can send it abroad themselves: here's what that takes.
