Only certain employees that have a specific need to review visa documentation will have access including our Immigration department which has expert knowledge of visa requirements, our Legal department in the context of any potential claim from the country of destination and restricted members of our IT team to ensure technical efficiency of the process.
Ground agents do not have access to your visa documentation other than viewing this information in the app on your device when they asked to see your saved visa documents as part of the visa checks on check-in.
