Follow TG102 in real time

The aircraft appears below whenever it is airborne and inside receiver coverage. Its planned route is drawn between the two airports.

TG102 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 08:00 at BKK. The full map has the rest of the sky, and what is flying over me will name whatever is above you instead.

TG102 route overview: BKK to CNX

TG102 distance and great-circle path

TG102 covers 596 km, or 370 miles. That makes it a short-haul flight, a single-aisle hop where turnaround time matters more than range. Of the 439 routes we track, it ranks 405 by distance.

The plane leaves Bangkok heading north. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the BKK-CNX route appears on a tracker map.

Why TG102 block time differs from cruise time

The schedule allows 1.3 hours from gate to gate. That works out to about 447 km/h. An Airbus A320 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Winds aloft shift the real flight time by up to an hour in either direction. See what really moves flight times.

Can the Airbus A320 comfortably fly TG102?

Not at all. At roughly 10% of its range, this is an easy trip for an Airbus A320. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A320.

What to know about TG102

  • Time change: none. Both cities keep the same clock, so arrival time reads exactly as you expect.

TG102 activity in the past 7 days

Our database contains 8 observations of TG102 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 7 distinct transponder addresses.

The median recorded visibility was 61 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does TG102 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A320, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown596 km
AircraftAirbus A320
Fuel burn rate2.91 kg per km
Fuel burned1,737 kg
CO2, whole flight5.5 tonnes
Seats, typical layout150
Passengers carried124 at an 83% load factor
CO2 per passenger44 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 44 kg cabin average and a flat bed well above it.

Economy132 seats, 110 flown
36 kg CO2 per seat
Business18 seats, 15 flown
104 kg CO2 per seat

Taken whole, TG102 emits what 91 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 260 km, or 1,265 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 3,984 km sector, the only published sector for this type, applied to this route's 596 km unadjusted. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put TG102 against another flight.

The route and typical schedule are maintained reference data. Live ADS-B observations are evidence of receiver coverage, not proof of on-time performance. Always confirm the operating date and times with the airline.
