| Attribute | Detail |
|---|---|
| IATA / ICAO | CCU / VECC |
| City / country | Kolkata, India |
| Direct destinations (catalogued) | 0 |
| Reached from (origins) | 1 |
| Based hub carriers | IndiGo and Air India |
| Coordinates | 22.655, 88.447 |
Coordinates are for checking, not decoration. CCU sits at 22.6547, 88.4467. That is genuinely useful when booking a room or a transfer, because “near the airport” is claimed to wildly different standards. In a large city, map distance and real travel time in peak hours diverge sharply — read the travel time for the hour you will actually move, not the kilometre figure.
IATA and ICAO are used in different places. The three-letter CCU is the IATA code that appears on tickets, bag tags and search screens; VECC is the four-letter ICAO code used in flight plans, notices to airmen and operational paperwork. IATA codes can collide for historical reasons; ICAO codes do not, and their first letters encode the region. A four-letter code in aviation documentation is not an error — it is a different system.
Airlines serving CCU
3 carriers appear at CCU in our catalogue and we hold an airline row for 3 of them, with baseline baggage spanning 7 to 25 kg. Alliances present: Star Alliance. 2 of them are based here. The field runs on Asia/Kolkata, ICAO VECC.
| Airline | Alliance | Baggage | Role |
|---|---|---|---|
| IndiGo (6E) | non-aligned | 15 kg | hub |
| Air India (AI) | Star Alliance | 25 kg | hub |
| Thai AirAsia (FD) | non-aligned | 7 kg |
The 7–25 kg range is two business models under one roof. The low end comes from unbundled fares that sell hold baggage separately; the high end from full-service carriers that include it. At the same airport those two desks price excess weight on different scales and by different methods. Connect between the two on separate tickets and a bag that cleared the first sector may not clear the second.
The alliances present here shape connections. Star Alliance operate at CCU, which opens through-checked bags and continuous boarding passes on a single ticket. The caveat: sharing a terminal with a partner logo does not mean your two flights are actually connected. The agreement attaches to the carrier pair and the ticket type, not to the building.
CCU route overview
CCU has 0 outbound corridors in our catalogue, roughly 0 departures a week All figures are estimates of the standard schedule. 1 of those corridors carry a cached fare, the lowest ฿8,940. The field runs on Asia/Kolkata, ICAO VECC. The corridors touching this field connect 2 countries in our catalogue.
Inbound
| Route | Freq/wk | Hours | Market low |
|---|---|---|---|
| Bangkok (BKK) → Kolkata (CCU) | 21× | 2.7 | — |
This field sits in our catalogue as a destination. We record 1 inbound corridors into it, splitting 1 short-haul (<4h), and no outbound guides — we build route pages only for journeys starting in Thailand. Departures from here exist; they simply have no page in this set yet. Read the carrier’s own schedule for the return.
Outbound and inbound are asymmetric because this is a catalogue boundary. We record 0 outbound and 1 inbound corridors for CCU. The gap reflects which route guides we chose to build — weighted to what travellers from Thailand search — not one-way service. The return flights exist whether or not we have published a page for them yet.
Corridors & fares from CCU
The 1 corridor at CCU break down as 1 short-haul (<4h), serving mainly ASEAN & regional leisure. We hold a cached fare for 1 of 1 route, the lowest ฿8,940 on BKK–CCU. Frequency across the corridors touching this field totals about 21 departures a week.
Most CCU corridors here serve ASEAN & regional leisure travellers. The mix is 1 short hop (under 4 h). Fares are shown in Thai baht (THB), and each route guide below carries live cached prices.
Why some rows have no price. We capture lows in passes, and not every corridor returns a value each time. Seasonal routes, thin routes and routes sold through narrow channels report irregularly. An empty cell means no capture succeeded in the latest pass — not that the route is closed or expensive. We leave it blank rather than interpolate, because plausible-looking estimates are exactly what makes a table untrustworthy.
Everything is shown in baht, and that matters more than it looks. Fares are converted to THB so they compare on one page, but the underlying prices are set in the currency of the market that issues the ticket. The same corridor can price differently issued in different countries, and the exchange rate moves between our capture passes. Read these as a ranking, not as accounting figures.
Direct flights to CCU — 1 route
Our catalogue records 1 inbound corridors into CCU from 1 country, block times 2.7 to 2.7 hours. Frequency figures are estimates combining every carrier on the corridor. Frequency across the corridors touching this field totals about 21 departures a week.
- BKK → CCU — 21×/wk, 2.7 h, low ฿8,940
How to read this list usefully. The frequency figure describes the risk in your plan, not the quality of the route: several departures a day gives you options when something breaks, a few a week means building in a spare day. We hold a cached fare on 1 of the 1 corridor here; the rest have no successful capture yet, which does not mean they cost more.
Direct destinations are not all reachable destinations. This list is the nonstop network in our catalogue. Everything else is reachable by connecting at a hub, which widens the choice and adds a point where the plan can break. If you must connect, make a single ticket the default and only split it when the saving is large enough to be worth the risk you are taking on yourself.
Time zone and connecting at CCU
CCU runs on Asia/Kolkata, 1.5h behind Bangkok. The gap is constant year-round. Every time printed on a boarding pass is local to that airport rather than an elapsed duration, so subtracting one from the other gives you the wrong number.
International-to-domestic is a full re-entry. At most airports that connection means clearing immigration, reclaiming the bag for customs, then checking in and passing security again — even on a single ticket. It takes materially longer than an international-to-international transfer. Plan around the actual steps rather than the gap printed on the itinerary.
Offsets make overnight flights deceptive. With CCU 1.5h behind Bangkok, a late-night departure can arrive the same morning or the next one on paper for identical flying time. That is the single most common reason transfers and first hotel nights get booked on the wrong date. Read the date on the final sector’s boarding pass, then confirm anything on the ground.
Minimum connection time is not in our data. Every airport publishes one, and the figure differs for domestic-to-domestic, international-to-international and terminal-change connections. A booking system will not sell you less than that on a single ticket — but it will happily let you build less than that yourself across two tickets. That is where passengers most often create risk without realising it.
