Important Safety Warning: Beware of fake customer service numbers on search engines. Only use official channels. Scammers frequently buy ads to promote fraudulent phone numbers. Jet2 staff will never ask for your account PIN, your myJet2 password, or ask you to move money to a “safe account” over the phone to process a refund.

Availability: The UK telephone support line is available Monday to Friday from 8:00 AM to 8:00 PM, Saturday from 9:00 AM to 5:00 PM, and Sunday from 10:00 AM to 5:00 PM (UK Time).

Timeline: Jet2 aims to respond to general complaints within 28 days. (Note: Under UK261 regulations, if your flight is delayed by more than 3 hours or cancelled due to reasons within the airline’s control, they must issue statutory compensation of up to £520 depending on flight distance, alongside any out-of-pocket expenses).
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If standard customer service cannot resolve the issue, you must formally escalate it to their Customer Relations/EU261 team. Send a written letter detailing your booking reference, a timeline of the issue, and your desired resolution. You must explicitly request a “Deadlock Letter” if they refuse your proposed resolution. Sending this via Royal Mail Signed For is highly recommended to prove receipt.
-
Complaints Address: Jet2.com Customer Care Team, PO Box 284, Leeds, LS11 1GE
-
Timeline: Under CAA regulations, Jet2 has a maximum of 8 weeks to issue a final resolution or a Deadlock Letter.
Level 3: Regulatory Authority (Government Ombudsman)
-
Authority: AviationADR
-
Portal/Contact: AviationADR is the CAA-approved, independent dispute resolution service for Jet2 complaints. You can submit a complaint online or by phone:
-
Website: aviationadr.org.uk
-
Phone: 0203 540 8063
-
Timeline (CRITICAL): You can only refer your complaint to AviationADR after you receive a Deadlock Letter from Jet2, OR if 8 weeks have passed since your initial formal complaint without a resolution. You must escalate the complaint to AviationADR within 12 months of receiving your Deadlock Letter.
Level 4: Legal Action (Final Step)
-
Pre-Litigation: Before commencing legal proceedings, UK legal protocols require you to send a formal “Letter Before Action” (LBA) to Jet2’s corporate legal headquarters. This letter must outline your claim, the exact legal or contractual breach, the evidence, and the financial remedy you seek, giving them a final 14 to 30 days to settle.
-
Legal Address: Jet2.com Limited, Low Fare Finder House, Leeds Bradford Airport, Yeadon, Leeds, West Yorkshire, LS19 7TU
-
Court: If the LBA fails and AviationADR cannot resolve it, you can file a lawsuit. For financial claims up to £10,000 in England and Wales, you can use the Money Claim Online (MCOL) portal to enter the Small Claims Track. For complex claims, you will likely need to instruct a solicitor and proceed to the County Court.
