flight fares sweden / london

hello everyone,

I did some preliminary search on flight fares with several options: trips to london and sweden (stockholm or stockholm + malmo), or trip to sweden only (stockholm or stockholm + malmo).
If the trip is to malmo, we would have to fly to copenhagen which is very near, either from london or from stockholm, or from san francisco. I´m not sure if going to both countries or the three of them would affect some people´s visas- I guess this could be a problem since we have such an international group.

The prices up to now are similar during all the month of february and start of march, I looked from saturday to saturday, for one week. It looks as it doesn´t change much with days or weeks, but of course, the closer it gets the more expensive it will get too.
Here are the approximate cheapest fares I found for these options:

OPTION 1. Visit to London and Sweden

San Francisco- London : 700$

OPTION 1A : London and Stockholm- TOTAL +- 800$

London- Stockholm (skavsta) (ryanair): 50-100$

OPTION 1B: London and Malmo- flights to Copenhagen (near malmo)- TOTAL +- 800$

London- Copenhagen : 100$

OPTION 2. Visit to sweden from stockholm

OPTION 2A : san francisco- stockholm (arlanda)- TOTAL +- 850$

between 800 and 900 $, via London, or US cities

OPTION 2B : Stockholm and malmo/ copenhagen: TOTAL +-970$

Stockholm- Copenhagen- from there road to malmo : 120 $ (norwegian airways)

OPTION 3. Visit to sweden from malmo:

the flight would be from san francisco to copenhagen, similar price than option 2 (around 800$), and from there if necessary round trip to stockholm (120$)

As for the fares, is doesn´t look as they change much with the week, so we might have to decide on a week to look closer.I can start to look at the cheapest hostel fares for these cities too.
