I am planning to travel to USA from Europe for a 6 month internship. The problem is that the return tickets for dates above 6 months are too expensive. Almost like buying two one-way trips (EU-US & US-EU).
Whereas return tickets for lesser duration are super cheap ($200-300 difference)
Will it likely be more expensive to buy discount one-way tickets to and from the US or a relatively expensive return ticket allowing a long stay?
