Airport at a glance

Our catalogue records 0 outbound and 2 inbound corridors at Indira Gandhi International Airport (DEL / ICAO VIDP), serving Delhi, India, across 4 carriers with 3 of them based here. Time zone Asia/Kolkata. Frequency across the corridors touching this field totals about 35 departures a week.

A base changes the outcome when things break. Air India, IndiGo and Air India Express are based at DEL, meaning aircraft, crew and operations staff sit on site. When a flight is cancelled the odds of a seat on the next rotation, or of a spare airframe, are far better at a base than at an outstation the carrier touches once a day. It is why the leg departing an airline’s own base usually recovers faster than the one returning to it.

Coordinates are for checking, not decoration. DEL sits at 28.5665, 77.1031. 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.

Airlines serving DEL

4 carriers appear at DEL in our catalogue and we hold an airline row for 4 of them, with baseline baggage spanning 15 to 30 kg. Alliances present: Star Alliance. 3 of them are based here. The corridors touching this field connect 2 countries in our catalogue.

“Serves” is not “flies daily”. This list covers every carrier appearing on a corridor into or out of DEL in our catalogue. Some fly seasonally, some a few times a week, and some sell as the marketing carrier on a partner’s aircraft. The number that matters to your plan is how many actually quote your dates — usually fewer than the full list.

The 15–30 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.

DEL route overview

DEL has 0 outbound corridors in our catalogue, roughly 0 departures a week All figures are estimates of the standard schedule. The corridors touching this field connect 2 countries in our catalogue. Block times on those corridors run from 4.4 to 5.5 hours.

Inbound

Outbound and inbound are asymmetric because this is a catalogue boundary. We record 0 outbound and 2 inbound corridors for DEL. 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.

This field sits in our catalogue as a destination. We record 2 inbound corridors into it, splitting 2 medium-haul (4–7h), 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.

Corridors & fares from DEL

The 2 corridors at DEL break down as 2 medium-haul (4–7h), serving mainly ASEAN & regional leisure. We hold a cached fare for 2 of 2 routes, the lowest ฿7,293 on BKK–DEL. Frequency across the corridors touching this field totals about 35 departures a week.

Most DEL corridors here serve ASEAN & regional leisure travellers. The mix is 2 medium sectors (4–7 h). Fares are shown in Thai baht (THB), and each route guide below carries live cached prices.

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.

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.

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.

The destination country sets the rules, not the departure airport. The corridors here span 1 country, each with its own aviation regulator, visa regime and transit conditions. What you are owed changes with the destination and the direction of travel, not with the airport you left from. The route guides carry the detail per corridor.

Time zone and connecting at DEL

DEL 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.

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.

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 DEL 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.
