Day Flight or Red-Eye? Strategy for Denver to Castries
On the 4-hour Denver to Castries corridor, choosing between a daytime departure and an overnight red-eye can significantly impact your trip. Day flights let you enjoy the full business class dining experience and arrive in the evening, ready for a hotel night's rest. Red-eye flights save a vacation day but compress your sleep window — on a 4-hour flight, you'll get roughly 3 hours of lie-flat sleep after dinner service.
