I’ll be making a quick trip to Florida at the end of the month. The three CO segments on the outbound leg will qualify for OP silver elite – no biggie for some of you guys – but it is to me. I return the next day on CO. What are the chances that the three flights will post and my elite level will actually process overnight? If it doesn’t, how can I get upgraded on the return? Also, what I can do to use the elite line through security? I know the OP pages states that elite benefits start the next day. Finally I’ll qualify silver elite on a Tuesday and then I have a trip on NW on Saturday. What can I do to ensure my elite level is communicated to NW so I can try for an upgrade on Saturday?

Thanks in advance.
