Also one way slightly under $500 USD. Add another economy segment of most airlines to continental Europe for less than $200 in most cases.
Ideal to re-position for much cheaper Europe-US/Canada J fares such as TP's CPH-US/Canada deals around $1500 USD rt. I did something similar like this 2 years ago with FI's one way Y+ fares for $700 (ended up sitting in Saga seats without the J food on both YYZ-KEF and KEF-HEL), and flew the reverse on TK's EU-YYZ J fares for $1600 USD. Those low fares are much rarer these days.
