Thanks for posting this deal. I was able to pair this with the US-UK Oneworld business class deal and it will make for a nice trip. I have been wanting to try RJ for a while and cant beat the price. Unfortunately on November 22nd they are using a A321 from LHR-AMM but I will survive.
Now the big question is what to do on my 6 hour layover on the return...I think I am too cheap to pay for the visa to allow me to go into town so may get to know the lounge really well on this trip.
