The festive rush is on, and snagging a last-minute flight home for Diwali can feel like a victory. But a cheap ticket with a layover can hide stressful surprises. Before you book, a few quick checks can prevent your journey from going off track.
Confirm Transit Visa Requirements
This is the
most critical check for international layovers. Many countries require Indian passport holders to have a transit visa even if you don't plan to leave the airport. Forgetting this can lead to being denied boarding on your first flight. For example, the UK generally requires a Direct Airside Transit Visa (DATV), and the US requires a C-1 transit visa or a valid visitor visa just to connect. However, popular hubs for Indian travellers like Dubai and Singapore often allow visa-free transit for short layovers if you stay within the international zone. Always check the specific rules for your nationality and layover airport on that country's official immigration website before booking. An existing visa for the US, UK, Canada, or Australia can sometimes exempt you from transit visa rules in other countries.
Verify Minimum Connection Time (MCT)
Every airport has a 'Minimum Connection Time' (MCT), which is the shortest legal time an airline can sell a connection. This can range from 30 minutes for a simple domestic transfer to over three hours for international connections. However, the MCT is an optimistic, best-case scenario. It assumes your first flight is on time and you can move quickly between gates. For last-minute Diwali travel, when airports are crowded, it's wise to book a layover that is significantly longer than the published MCT. A good rule of thumb is to allow at least 90 minutes for a domestic connection and a minimum of two to three hours for any international transfer, especially if it involves immigration.
Understand the Baggage Transfer Policy
Don't assume your checked luggage will automatically be sent to your final destination. If you booked your flights on a single ticket with the same airline or partner airlines (under a codeshare agreement), your bags are usually transferred for you. However, there are crucial exceptions. When connecting in some countries like the United States, you almost always have to collect your bags, clear customs, and re-check them for your onward flight. The same applies if you have an overnight layover or if your connecting flight is more than 12 hours later. The biggest risk is with 'self-transfer' flights booked on separate tickets. In this case, you are always responsible for collecting and re-checking your luggage, which adds significant time and risk.
Check for Airport or Terminal Changes
A cheap connection might involve more than just walking to a new gate. Some layovers require changing terminals or even airports. Large international airports like London Heathrow or Delhi can have terminals that are far apart and require a bus or train ride to travel between them. Sometimes, this transfer happens 'landside', meaning you have to exit the secure area, officially enter the country, and go through security screening again. This process can easily consume an hour or more. Always check the arrival terminal of your first flight and the departure terminal of your second. If they are different, research the transfer process and time required before you commit to the booking.
Clarify 'Self-Transfer' Risks
Many online travel agents sell 'self-transfer' or 'unprotected' connections by combining separate tickets from different airlines. While these can be cheaper, they carry significant risk. With a self-transfer, the airlines have no obligation to help you if you miss your connection due to a delay. You are treated as a 'no-show' for the second flight and may have to buy a new, expensive last minute ticket. These itineraries are only advisable if you have a very long layover (five hours or more) and are travelling with only carryon luggage, as you must collect and recheck any bags yourself. Always read the fine print to see if your connection is protected or a self transfer.
Review Health and Document Formalities
Even with pandemic era rules relaxed, some health and documentation requirements remain. For instance, all international passengers arriving in India may still need to complete a self declaration form like Air Suvidha before arrival. During last minute rushes, it is easy to forget these steps. Before you travel, ensure your passport is valid for at least six months and that the name on your ticket exactly matches your government issued ID. For domestic travel within India, ensure you have an approved original photo ID, such as an Aadhaar card, passport, or Voter ID.
