IIRC, doesn't Heathrow's "free" wifi want a name and/or email address before it lets you onto the net?

Perhaps it's cross-referencing your name w/boarding records for security purposes.

Yes, but the flight number is displayed before you submit your email address.

Southwest WiFi seems to do this, and unlike Delta it is available under 10k feet, gate to gate. Something about satellite based vs. ground station based.
