Hi Monica,
I'm not sure what your problem might be, I have successfully found a
Dublin/Rovaniemi return flight using Azuon, which seems to be cheaper
than what skyscanner found to you.
What you found costs 27.99+61.86+94.90+39.28+54.40=278.43 EUR
What I have just found using Azuon:
Ryanair Dublin (DUB) London (Stansted) (STN)
Thu, 17 Mar 06:25 Thu, 17 Mar 07:45 13h 35 15.99 EUR
Ryanair London (Stansted) (STN) Tampere (TMP)
Thu, 17 Mar 12:30 Thu, 17 Mar 17:10 33.23 EUR
airBaltic Tampere (TMP) Rovaniemi (RVN) Thu, 17
Mar 20:40 Thu, 17 Mar 22:00 32.39 EUR
airBaltic Rovaniemi (RVN) Hamburg (HAM) Sun, 20
Mar 07:20 Sun, 20 Mar 12:55 11h 50 73.63 EUR
Aer Lingus Hamburg (HAM) Dublin (DUB) Sun, 20
Mar 16:10 Sun, 20 Mar 17:10 86.61 EUR
This is altogether 241.85 EUR.
So Azuon finds a cheaper route than skyscanner, is it a problem?
Could you attach an XML file from your search query? This may help to
check what you configured somehow else than me.
You are right that skyscanner is free, but there are some differences
compared to Azuon.
E.g.
you can configure a lot more things using Azuon <-> there are only a
few settings in skyscanner;
skyscanner uses cached fares so it's not sure that what you see is the
real price <-> Azuon gets the fares directly from the low cost
airlines websites;
and there are a couple more.
Of course it may happen that Azuon does not show all the routes that
skyscanner does. This is mainly because Azuon is under development, so
with donating a small fee, we are supporting the developers, who try
to make it more "clever".
Best,
