Sorry for the silly questions; I'm new at this.
I understand the above posts to say that after I arrive at Heathrow terminal 3 on Delta flight 10 in Delta One class (scheduled arrival at 0755) and clear customs, I can use the Virgin Atlantic arrivals lounge. Did I get that right? In case it matters, I am flying on an award ticket issued by Air France.
On a related note, what are my options before departure from MSP?
Thanks for any help you provide to this novice.
