Report Has Interjet gone out of business? in Ajijic/Chapala/Guadalajara Posted March 30, 2020 I was having the same problem and made a last ditch effort. Googled Interjet Customer Service Complaints and called 55 1102 5511 on March 28. Asked for someone who spoke English and got through quickly. Because I had booked the "light" option, I could not get a refund and had to rebook............picked a random date in the fall and was charged the $3.38 difference in the price. Suspect I will change the date but it was a cheap way not to lose all the ticket cost. She did tell me that changes must be made 24 hours before flight time so good luck as flight date is come and gone but worth trying.
