Return check-in?
 

IAD-TPA-IAD in same day.

Is OLCI the day before for both flights OK, that is, can one check-in for the return before the outbound flight?

Thanks.

It has been my experience on the last 2 MR's that it only lets you check in for the first set of segments. If it is an RT, then it is the outbound. If it was a multi-city, then it is the first grouping shown on the itinierary. You'll have to get the other BP's at the airport. Either a counter or an RCC.

Here's the related thread -

Mr. Chicken Online doesn't allow you to check in for the return legs until the outbound legs have been flown. Just ask a GA in TPA to check you in and print your BPs; they may give you a funny look as they wonder how you got past security w/o a BP, but they'll be able to print the BP without a problem.

or you can check-in at the counter of your starting point for both the outbound and return (or a combo of on-line/mr.-ms. easy and then go to the counter for the return bp). works all the time for me at sfo ^
