According to easyJet's official policy, you do not strictly need to include your middle name when making a booking, as long as your first name and last name exactly match the machine-readable zone at the bottom of your passport. EasyJet’s systems are designed to match the primary identification details, and they are generally more lenient than long-haul international carriers regarding middle names. However, if your middle name is included as part of your first name on your passport (e.g., "John David" under the First Name field), it is safer to include it to avoid any potential confusion at the boarding gate. If you have already booked and realized you missed your middle name, there is no need to panic or pay for a name change, as this is not considered a significant discrepancy. The airline focuses on the accuracy of the surname and the first initial to ensure security compliance. As long as your travel documents are valid and the primary names align, you will be permitted to fly without issue.
