Cheapest economy fares often exclude checked baggage, seat selection, and priority boarding, so factor in ancillary fees when comparing total cost. Nearby major cities commonly reached with economy fares include New York, Los Angeles, Chicago, Miami, and Seattle.

To secure the cheapest economy flights in April, monitor fare alert tools, book midweek departures, and compare low-cost carriers with legacy airlines.
