Thanks for your feedback - I appreciate it.
None of the above cases represents my situation though. I have a confirmed ticket with the OTA and LATAM but missing the coupons. Now the question is about who has deleted them. Strong evidence that IBERIA has done so. I did not call for cancelation. But Iberia says - "You can not fly that ticket but we have not touched it." LATAM same. OTA same. Ticket under airport control. Noone can touch it.
Flight next Tuesday.
Intersting case.
Can i ask which coupons you mean? I have a confirmed ticket with the OTA and it also shows up in every of the airline engines unchanged for now.
