Anyone know why UA online check-in doesn't have an option for travelling on visas? If you are not a perm res, or ESTA you can never check in online when to the US. Always end up doing it at airport.

Other airlines (LOT, BA, VS) , all have the ability to enter visa details and check in onlie but not UA.

Curious why this is the case with UA. it's no big deal, but I am curious.

Anyone got any ideas?
