Spirit and other airlines have been struggling with high oil prices that have pushed up the price of jet fuel. The company’s woes predated the war in Iran, though, as the company has struggled to increase post-pandemic demand.

Well yeah, the population that would normally fly Spirit are now unable to afford flying at all.

Do you happen to live in North America? If so I’d highly recommend checking out the Xerces society plant lists for recommended species that support local pollinators. The plant lists include timing info for suggestions on what would bloom the rest of the year, because as you mention lilacs are fairly short bloomers (might I recommend my namesake, the humble fireweed, which is a late summer bloomer?)
