A gate agent saved the connection

I was already stressed when the inbound aircraft reached New York JFK late on Jan 3, 2026. Renee at the gate checked the Thai Lion Air app, moved me to an earlier boarding lane for SL676, and called ahead so the crew knew I was coming. I made the Toronto Pearson connection with only a few minutes to spare. It was the kind of calm help that changes the whole trip.

complaint · Baggage ★★☆☆☆

Baggage updates stopped after the first claim

My suitcase did not arrive at Paris Charles de Gaulle on Apr 3, 2026. The first agent filed claim SL-5401 and sounded confident, but after that the online tracker barely changed. I called twice, got two different answers, and bought basic clothes without knowing what would be reimbursed. The bag eventually appeared, but the silence was more frustrating than the delay itself.

complaint · Refunds ★★☆☆☆

Refund request kept getting closed

I cancelled within the permitted window and uploaded the receipts for Thai Lion Air SL750. The refund case showed as closed even though the $214 credit never posted. Each chat agent told me to wait another billing cycle. I do not mind a process, but I do mind starting from zero every time I contact support.

complaint · Boarding ★★★☆☆

Boarding group treatment felt unnecessary

At Madrid Barajas on Oct 21, 2026, our boarding group 5 was called and then held to the side while several later passengers were allowed through. No one explained the change. The flight was fine once we sat down, but the tone at the door made the start of the trip feel disorganized and dismissive.

complaint · Seats ★★☆☆☆

Family seats were split after payment

We paid to keep our family together on Thai Lion Air SL824 from SIN to SYD. At check-in, two of the 2 children were assigned several rows away. The airport team fixed one seat but not all of them, so another passenger had to trade. Families should not have to negotiate at the cabin door after paying for seats.

review · Staff ★★★★★

Clean cabin and a crew that noticed details

The cabin on Thai Lion Air SL861 was clean, and the crew noticed small things without being asked. On Apr 13, 2026, a passenger near me was nervous during turbulence, and a flight attendant checked back twice with water and a quiet update. Nothing dramatic happened, which is exactly why the trip felt professional.

complaint · Customer Service ★☆☆☆☆

Could not reach anyone during a schedule change

Thai Lion Air changed my departure from Tokyo Haneda by several hours. The email said I could choose alternatives online, but every option ended with an error. I waited 37 minutes on the phone and then the call dropped. By the time I reached an agent, the better connection was gone.

review · Accessibility ★★★★★

Wheelchair assistance was handled with care

My mother needed wheelchair assistance for Thai Lion Air SL935. At Terminal 4, the escort arrived before boarding, stayed with us through security, and made sure the destination team at Dubai knew where to meet her. It made a difficult travel day feel manageable.

complaint · Price ★★★☆☆

Seat fee was charged twice

I selected a standard aisle seat for Thai Lion Air SL972 and saw two separate $88 charges on my card. The website showed only one seat purchase, so I had to send bank screenshots to prove the duplicate billing. The duplicate was corrected, but only after three messages.

complaint · Online & App ★★★☆☆

App boarding pass disappeared at security

The mobile boarding pass for Thai Lion Air SL119 loaded fine at home, then disappeared at Delhi security on Apr 3, 2026. The kiosk printed a new one, but I had to leave the line and start over. The staff helped, but the app made a simple trip more stressful than it needed to be.
