I have a cruise booked from Reykjavik to Southampton September 2027. No that is not a typo: 2027. (Beginning research early)
I was looking at flights just to get an idea of how I will be going and coming.
Google Flights suggests that I book a one way ticket each way on a different airline. and that i do the booking one after the other.
So doing mock flights:
I would be flying Delta to Reykjavik with one stop but flying home from London on American non stop.
Prices were good even one way. I did not get any warnings about having a return ticket.
Could there be any problems booking one way on different airlines?
I tried multi cities but results were not as good as booking one way.
