WATCH: Mark Murphy on 737 Max Grounding, Cruising and Travel Agents

There are a ton of hot topics in travel heading into this summer but perhaps none more captivating among American travelers than the ongoing grounding of the troubled Boeing 737 Max aircraft.On Tuesday, travel expert Mark Murphy appeared on Fox News to discuss the grounding's potential impact on summer travel in addition to the value of a cruise vacation and using a travel agent in 2019."I think it's been way overblown. The reality is the airline that flies the most [737 Maxs] is Southwest Airlines with 34 planes, followed by American Airlines with 14 and United Airlines has 14 of the Max 9s. If you're flying Miami to New York, that's the heaviest traffic route for that plane. Other than that, it's less than five percent of any airline's total flights. It should have no impact on any travelers because the airlines have had plenty of warning to bring in other planes to backfill," said Murphy. "They've also increased capacity this summer because demand is way up."
