I suppose. My instructors have always filed DXR-ABC and then ABC-DXR,
with a full stop to pick up the new clearance. They have said that round
robin flights can be a problem. I've never tried it myself.


The "problem" is probably due to not filing a delay at the point where the
approaches are to be flown. If an hour of approaches is desired, the format
would be DXR..ABC/D1+00..DXR. Without the appropriate delay you'd be
overdue one hour at all posted fixes between ABC and DXR. If ABC is served
by an ARTCC the computer will generate time updates, but that gets annoying.
