British Airways
For necessities like prescription medications, smartphones, other electronic devices, and passports, you can bring a small bag. This is guaranteed to travel with you in the cabin as part of your British Airways baggage allowance. If there is space, you may bring a larger bag into the cabin. Electronic devices with lithium batteries, replacement batteries, and power packs should be kept in your smaller handbag since these are not permitted in the hold, along with prescription medication, travel documents, and valuables. Before taking off, you must check in your checked baggage. Please clearly mark your name and any other contact information, like a phone number or email address, on the inside and outside of each of your checked bags.
You can pay extra baggage fees if you need more than the standard amount allowed by British Airlines. You are allowed to bring everything that is important to you, including your musical instruments and athletic gear. You can also find out about excess baggage and unclaimed or lost baggage.
