Houston-based low-cost carrier Avelo is celebrating its third birthday as it soars into its next year of success. On the eve of its birthday, it also announced it would connect two Floridian cities, Miami and Orlando. The airline is showing no signs of slowing down, with the airline expected to launch 17 new routes in the next 60 days. To celebrate Avelo’s birthday, a promo code “3YEARS” offers $30 off tickets across the carrier’s network for the upcoming summer.
