The 'One Cabin Bag' Rule Explained
The most significant change travellers are facing is the strict enforcement of the 'one cabin bag' rule by India's Bureau of Civil Aviation Security (BCAS). While the rule itself has existed for years, airlines and airport security are now universally
enforcing it across all domestic and international departures from India to reduce congestion and improve on-time performance. For most economy class passengers, this means you are permitted one primary cabin bag weighing a maximum of 7 kg. Your handbag, small backpack, or laptop bag must fit inside this single piece of luggage; it is no longer considered a separate personal item that can be carried alongside a trolley bag.
What Still Counts as a 'Personal Item'?
While the main rule consolidates luggage into one bag, some airlines do specify a small additional allowance. IndiGo, for example, allows one personal article like a ladies' purse or a small laptop bag not exceeding 3 kg in addition to the 7 kg cabin bag. Air India also mentions an allowance for a personal item that can fit under the seat in front of you. Generally accepted items across many carriers, as long as they meet size limits, include a ladies' handbag, a small laptop bag, a camera, or reading material for the flight. However, the key is that this item must be small. A bulky backpack will not qualify and you will be asked to check it in. To be safe, always assume the 'one bag' rule is absolute and be prepared to consolidate your items if asked.
Know Your Airline's Specific Limits
While the BCAS sets the overriding security framework, individual airline policies on weight and dimensions still apply and can vary. The standard cabin bag weight for economy class is 7 kg for most domestic carriers like IndiGo, SpiceJet, and Akasa Air. Air India is slightly more generous, sometimes allowing 8 kg domestically and having different rules for its premium classes. Dimensions are also critical. The common size limit is around 55 cm x 35 cm x 25 cm, but you must check the exact dimensions on your airline’s website before you pack, as a bag that is too large will be moved to check-in.
Packing Smart for a Single Cabin Bag
This stricter enforcement means travellers need to be more strategic with their packing. Start by wearing your heaviest clothing items, like jackets and boots, on the plane. Use packing cubes to compress clothing and save space. For electronics, remember that power banks and any spare lithium batteries must always be in your cabin luggage; they are prohibited in checked baggage. Liquids, gels, and aerosols must be in containers of 100 ml or less, all placed within a single transparent, resealable one-litre bag. To avoid last-minute surprises, weigh and measure your packed cabin bag at home before leaving for the airport.
Check-in Baggage: Pre-Book to Save
For check-in luggage, policies differ significantly based on the airline and the fare you purchased. Most domestic economy tickets include a 15 kg checked baggage allowance, though Air India often provides a more generous 25 kg. Be aware that many budget airlines sell 'lite' fares that do not include any free checked baggage. If you need more than your allowance, the most important tip is to purchase extra baggage online in advance. Buying extra weight at the airport check-in counter is always the most expensive option, often costing significantly more per kilogram.
