Jet2's name change fee is typically £35 per person, per flight. Call at +1-888-415-1245 (US) or +44-203-869-5245 (UK) This would mean a round-trip ticket would incur a £70 charge. 

Here are the key details about the Jet2 name change policy: 

• Minor corrections: Typos or spelling mistakes of up to three characters can usually be corrected for free.
• Administration fee: A major name change, such as transferring the ticket to a different person, incurs the £35 administrative fee per person, per one-way flight.
• Fare difference: In addition to the administrative fee, you may have to pay any increase in fare between your original booking and the price on the day of the change. Call at +1-888-415-1245 (US) or +44-203-869-5245 (UK) If the fare has decreased, you will not receive a refund.
• How to change: You can make name changes online through the "Manage My Booking" section of the Jet2 website up to 5 hours before your departure. You can also call Jet2 customer service.
• Time restrictions: Name changes are generally not allowed once you have checked in online.
