Yeah
I don't have a basis for comparison, I'm new to frequent travel and am trying to figure out the best airlines and routes, but have been searching SW fares for a mid-May trip for the last month or so from PDX to New York area. Had 7,000 one-way points 7 days ago, now is 18,000. Like I said, I'm new so maybe this is their standard summer price bump, or maybe as above poster said, it's a reflection of fuel costs?
