We got discount codes at this Easter event. Apparently you get 10% off domestic travel in Tango with code MQVEFEF1 or 10% off Tango Plus with J3ZUG941. We tried them and they seem to work. Found out in the meantime that you have to book and travel by July, 15th and they might discontinue it anytime.Does anyone know a code for business class to US? Got a cruise from San Diego coming up soon.
