I will be arriving at LHR Terminal 2 on a United Polaris flight and would like to take advantage of the Polaris Arrivals lounge. I need to check my bag for a flight to KEF on Icelandair (traveling on 2 separate tickets so can't check my bag through all the way to KEF).
Will I be able to take the elevator up to the Check in level , drop off my bag then come back down to the Arrivals area & use the lounge?
