Emirates is widely regarded as one of the stricter airlines regarding carry-on weight, particularly for Economy Class passengers. The standard allowance is a single piece not exceeding 7kg (15 lbs). In major hubs like Dubai (DXB), ground staff frequently weigh cabin bags at the check-in counter or even at the boarding gate. If your bag looks bulky, they are highly likely to intervene. Business and First Class passengers have more leeway with two pieces at 7kg each, but the limit per piece remains firm. While you might occasionally encounter a lenient agent, the "Emirates way" is to enforce these rules to ensure cabin safety and overhead bin availability. If your bag is found to be over the limit at the gate, you may be forced to check it, which can incur significant "excess baggage" fees if you have already hit your checked luggage quota. To avoid stress, it is best to treat their 7kg limit as a hard cap rather than a suggestion.
