This Time Forever by Constance O'Day-Flannery (1990)

FLIGHT TO PARADISE
Insurrectionist Meggie Billbride had a premonition something would go wrong when she planted the bomb at the mining company offices. Still, the hot-tempered revolutionary refused to back out of her mission . . . and when the dynamite exploded she was certain she was sailing toward the pearly gates. Instead, she discovered she was in a flying machine of the future and seated next to the most handsome mortal she'd ever seen! And as Meggie met his kind emerald gaze and sought his confidence and comfort, the disoriented beauty's terror of her predicament was soon replaced by flaming hot passion!

HEAVENLY MIRAGE
Fantastically rich Thomas Carter was about to complain about his first-class privacy being disturbed, but when he saw the oddly-dressed goddess beside him, his outrage turned into curiosity. Her slight Irish accent, her quaint hairstyle, and her fresh bright attitude intrigued him much more than all the modern worldly women who had been his usual female fare. The worldy tycoon wasn't satisfied with imagining what lay beneath the high-necked dress. He swore to pursue her relentlessly until he had won her, for now and for always!
