What steps will reproduce the problem?
(1) Take a Lufthansa flight
(2) Try to use the WiFi
(3) Observe that the captive portal just takes you to a white page that doesn't load anything

What is the expected output?

Bring to a login/pay prompt. Safari seems to work here.

What do you see instead?

A white page that doesn't take you anywhere. During loading, I notice some tiny gray boxes that look like those "right click to enable flash", but then they disappear, so I think this has something to do with logic to disable flash.
