Timing on flights to Europe?

I haven’t flown to Europe in ages so I’m out of the loop on the best time to book. We’re heading to France and England in July and right now the cheapest I can find is around $1500pp. Is that roughly what flights are costing these days, or should I wait to see if it drops at all? I remember getting round trips for $500pp not too long ago, but I know inflation has been rough all around. Departing from Portland, OR US
