Note that both your personal item and carry-on bag (referred to as hand baggage) combined must not weigh more than 26 pounds if you're traveling economy. The weight limit is 40 pounds for premium economy and other higher-class cabins.

As of early 2026, the weight limit for a free carry-on bag varies drastically by airline and region. For major full-service US carriers like Delta, United, and American Airlines, there is typically no specific weight limit for carry-on bags, as long as the passenger can lift the bag into the overhead bin unaided. However, international and budget carriers are much stricter. Many European and Asian airlines, such as Air India and Lufthansa, cap the weight at 15 to 17.6 pounds (7 to 8 kg) for economy passengers. British Airways is a notable outlier, allowing up to 51 pounds (23 kg) for a carry-on, though size restrictions still apply. On "Ultra Low-Cost Carriers" (ULCCs) like Frontier, Spirit, or Ryanair, a standard "carry-on" (the large bag for the overhead bin) is almost never free and often comes with a weight limit of 22 to 35 pounds if purchased. Always check your specific 2026 fare class, as "Basic Economy" tickets often strictly limit you to one small personal item under the seat.

Yes, Uber is fully operational at all major London airports in 2026, including Heathrow (LHR), Gatwick (LGW), Stansted (STN), and London City (LCY). However, because of London's strict private hire regulations, you cannot simply walk out to the curb and hail one. At Heathrow, for example, you must follow signs for "Passenger Pick-up" or "Short Stay Car Park," as each terminal has a designated row specifically for rideshare apps like Uber and Bolt. In 2026, Uber offers several tiers in London, including Uber Green (electric vehicles), which is often encouraged to avoid the city's Ultra Low Emission Zone (ULEZ) charges. Pricing from Heathrow to Central London typically ranges from £45 to £80, depending on traffic and surge demand. It is worth noting that for a more "traditional" experience, London's iconic Black Cabs are available at the taxi ranks directly outside the terminal doors; while they are often more expensive than Uber, they have the legal right to use bus lanes, which can save significant time during the heavy London rush-hour traffic.
