Extra costs...
On the skyscanner website they where cheaper so I choose to book via them only to find out that i had to pay 250 dollar at the airline for the 2 seats thank you very much
So it is not cheaper and these compare sites are misleading. The reply from trip.com that i get free seats assigned is true but then you end up in the middle row and probably not next to your travel partner. So lessons learned here i will never ever use trip.com anymore.
