After watching the fluctuating flight prices for several days for Mid-March I just booked one way ticket in and one way out ticket for less than round trip price.
I paid $134 - $54 tx = $188 fm EWR to POP and see it's now POP to EWR $283 total.
That's $471 instead of $497 for Round Trip.
I've done this a few trips and just thought I'd point out that it's something to consider booking two one-way tickets instead of round trip.
The difference can mean a TLN or ST.
