Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14.

In 2026, the number of checked bags allowed depends on your airline, route, and fare class. Most international full-service carriers (like Air India, British Airways, or Delta) permit two checked bags (up to 23kg/50lbs each) in Economy for transoceanic flights. However, for domestic travel or "Basic Economy" fares, the allowance is often zero, requiring you to pay for each bag (typically starting at $35–$40 for the first). For those departing from India in 2026, be aware that the Bureau of Civil Aviation Security (BCAS) has strictly enforced a one-piece cabin bag policy, meaning only one bag (max 7kg) is allowed in the cabin, forcing many travelers to check their second personal items or handbags. Always verify your specific "allowance" on your e-ticket, as "low-cost" carriers like Ryanair or IndiGo now exclusively use "unbundled" pricing where every checked bag must be purchased separately.
