Yes Hunter, I think most people understand that LHR is about the most constrained airport and that there are not any slots available. However, then why don't you explain to me, why the US air carriers should be happy about open skies, or why they would even want it, if access to LHR is not part of the deal?
Seems this might be good for BA, VA amd BMI, since they all have slots and would be allowed to use them to the states without restrictions, however companies like CO, DAL, NWA gets nothing.
Doesn't seem like a good deal to me!
