JSX reviews and complaints
Recent traveler stories about JSX flights, connections, baggage, schedule changes, and customer service.
Pet reservation was confirmed but missing
I called before travel to confirm the pet-in-cabin reservation for JSX XE162. At Delhi, the record was missing and the agent had to call a supervisor while the line grew behind me. We eventually boarded, but the confirmation should have been visible from the start.
A crew member handled a tense cabin well
There was an argument over overhead bin space before JSX XE199 pushed back. Daniela kept the tone calm, found space several rows forward, and avoided embarrassing either passenger. That kind of cabin control matters.
Miles did not post after repeated requests
The miles from JSX XE236 to Doha Hamad never posted. I submitted the boarding pass, ticket number, and receipt twice. The reply kept saying the trip was not eligible, but no one explained why. Loyalty programs should not make customers chase basic credit.
Security document check was organized
For an international departure from Singapore Changi on Apr 5, 2026, JSX had a separate document check before bag drop. The line looked long but moved steadily, and agents were clear about passports, visas, and onward tickets. I appreciated the organization.
Maintenance delay was explained poorly
I do not blame JSX for checking a maintenance item on XE310. Safety comes first. What bothered me was the lack of updates: first ten minutes, then another twenty, then silence. Passengers can handle delays better when someone explains the plan honestly.
Arrival team helped after a medical scare
A passenger near us felt faint before landing on JSX XE347. The crew asked for medical help, kept the aisle clear, and arranged for staff to meet the aircraft at London Heathrow. It was handled respectfully without creating panic in the cabin.
A gate agent saved the connection
I was already stressed when the inbound aircraft reached Miami late on Jan 18, 2026. Renee at the gate checked the JSX app, moved me to an earlier boarding lane for XE384, and called ahead so the crew knew I was coming. I made the Dubai connection with only a few minutes to spare. It was the kind of calm help that changes the whole trip.
Baggage updates stopped after the first claim
My suitcase did not arrive at Toronto Pearson on Apr 10, 2026. The first agent filed claim XE-7882 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.
Refund request kept getting closed
I cancelled within the permitted window and uploaded the receipts for JSX XE458. The refund case showed as closed even though the $154 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.
Boarding group treatment felt unnecessary
At Los Angeles on Oct 22, 2026, our boarding group 3 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.
Family seats were split after payment
We paid to keep our family together on JSX XE532 from MAD to DOH. 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.
Clean cabin and a crew that noticed details
The cabin on JSX XE569 was clean, and the crew noticed small things without being asked. On Apr 19, 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.
