Before making a complaint
Note: To lodge a complaint against TUI, you must have initially addressed your issue directly to TUI’s customer service in writing so make sure you contact TUI first.
You should have received a final written response (commonly referred to as a ‘deadlock letter’) from TUI or given TUI an eight-week window to answer your complaint.
AviationADR exclusively handles unresolved complaints.
