US to VCE/BCN question

[Davide]

I've just noticed that US plans to anticipate the beginning of 2 seasonal routes to Europe the next summer. US will restart PHL-Barcelona and PHL-Venice on Apr 10 this time, one month earlier than usual. All the other seasonal flights (Shannon, Glasgow, Lisbon, Stockholm, Athens) will begin from the 2nd/3rd week of May.
I wonder if this means that VCE and BCN will become the next year-round stations for US.

Could it be that VCE and BCN have popular, well-attended religious events during the Easter season? (Easter is April 27 in 2008.)
