Without doubt, as noted above, this is an absurd price for a low-cost carrier.

Even more though, I wonder why the OP even shared this without doing any research, given that one can find much lower prices, also when one sticks to the noted Thursdays ... And where does the $400 per seat per direction come from anyway?

For example, when booking directly via LL website return LAX BCN on 12/3 + BCN LAX on 19/3 costs $1162 for Premium Light, $1322 for Premium Comfort, $1512 for Premium Extra.

I am happy when members are making an effort to share, however I would appreciate some focus on quality as well ...
