Flight-booking site Kayak rolled out a brand-new search feature Friday in which allows users to exclude specific plane versions coming from their options, following Sunday’s deadly crash of a Boeing 737 Max 8 jet in Ethiopia.

Passengers don’t need to worry about flying in 737 Max versions today, because the Federal Aviation Administration on Wednesday joined regulators around the planet in grounding the planes. The FAA cited brand-new evidence in which showed similarities between the Ethiopia crash as well as another deadly one involving a 737 Max 8 almost 5 months ago off Indonesia.

However, airlines expect the Max versions to be grounded for only a few months as well as will likely be booking flights on these versions for later on, said Steve Hafner, co-founder as well as CEO of Kayak, a unit of Booking Holdings, formerly Priceline. They’re out of service on a temporary basis, he said on SouthIndianNews.com’s “Squawk Alley.” “In reality, airlines are still planning on flying those planes inside summer. People want security as well as comfort when they fly.”

Booking rates on Kayak haven’t been going down, Hafner said, adding in which the site has seen more search activity as people try to make alterations to their disrupted flights.

“In reality, the 737 Max isn’t in which widespread inside U.S.,” Hafner said. Only 74 of the more than 370 Boeing 737 Max jets are flown by U.S. airlines. However, the series can be one of the company’s top sellers. Boeing can be creating 52 of these versions per month in order to keep up with the 3,800 orders, he said.

Shares of Boeing plunged following Sunday’s crash, losing $26.6 billion in market value on Monday as well as Tuesday. yet the stock rose more than 2 percent Friday, following a report in which the company plans to roll out a software fix sooner than expected.
