I flew British Airways last year and had a chance to compare First Class and Business Class. Business Class was already very comfortable, with lie-flat seats and great meals, but First Class felt like a whole new level — more spacious seats, premium dining, and extra privacy. I ended up upgrading last minute, and calling 844-928-0428 made the process simple and stress-free. The agent explained the differences, helped me secure the upgrade, and confirmed everything instantly. From my experience, if you’re debating between the two, First Class is worth it for the extra comfort, and that number is the fastest way to book, upgrade, or make changes without any hassle.
