The pandemic devastated airlines in 2020 and forced many out of business - here's the most notable that didn't make it to 2021

• Last year saw an influx of airlines close up shop as the pandemic forced travelers to stay home. 
• All 11 major US airlines remained intact but smaller regional carriers were forced to close or merge due to the drop in travel demand. 
• Not all were due to the pandemic, however, as the first two months of the year saw high-profile closures due to mounting losses.

Each year sees a small number of airlines close up shop for any number of reasons, but last year had the pandemic to speed some along. 

A surprise announcement in February that the promising Qatar Airways-backed Air Italy would be liquidated set the stage for a year of losses even before lockdowns grounded the world's airlines. And while the coronavirus was well-known by then, its destructive power in the airline industry was still yet to be realized. 

In the US, all 11 major airlines remained intact but smaller regional carriers folded amid an unprecedented drop in passengers that remains low even into the new year. Three carriers operating flights on behalf of larger carriers both closed up shop after their services were no longer required by the majors, costing thousands of jobs in the industry amid an already grim period of furloughs.

Here are the most notable airlines we said goodbye to in 2020.

Compass Airlines

Compass Airlines was a regional airline that shut down in April 2020 after ending operations with American Airlines and Delta Air Lines, according to FlightGlobal. The Minneapolis-based carrier primarily flew the Embraer E175 aircraft with bases on the West Coast in its last years. 

ExpressJet Airlines

ExpressJet Airlines was a regional airline that ceased operations on September 30, 2020, after United Airlines chose rival CommutAir to fly regional services. Major airlines like American Airlines, Delta Air Lines, and most recently, United Airlines had contracted the airline to fly its regional hubs to smaller cities. 

One pilot who flew for ExpressJet described the airline to Insider as reliable and professional to the end, earning the nickname "SureJet." 

 "We were the little airline that could," Colin Crane, a former ExpressJet pilot, told Insider in a prior interview.

The carrier had a small stint as an independent airline selling its own tickets and flying its own routes but rising oil prices at the time put an end to that plan. 

Ernest

Italy's Ernest suspended operations less than two weeks into 2020 after only five years of service, AirlineGeeks reported. The carrier primarily served European destinations with a fleet of four Airbus aircraft. 

AtlasJet

Turkish carrier AtlasGlobal suspended operations in February 2020 after having just resumed operations following a challenging economic environment in its home country, according to FlightGlobal. The airline operated flights within the Middle East and Europe with an Airbus fleet.

Trans States Airlines

Trans States Airlines was a regional airline that flew Embraer ERJ145 services for United Airlines, While originally planning to cease operations by the end of 2020 after consolidating operations with ExpressJet Airlines, the pandemic saw the airline cease operations on April 1, as Insider's David Slotnick reported.

Its parent company, Trans States Holdings, was also the parent company of Compass Airlines.

Air Italy

Air Italy was an Italian airline reborn in 2018 under new ownership and strong backing from Qatar Airways. The airline could trace its routes back to the 1960s and flew under the Meridiana brand from the early 2000s until its rebrand. 

Meridiana and the former Air Italy had combined to create an airline to rival Alitalia. The first new intercontinental flight launched to New York from Milan in June 2018 with subsequent expansions across the US and Canada. 

Operations were ultimately ceased in February 2020 as its first years saw massive losses, as Insider's David Slotnick reported. The Boeing 737 Max grounding had also cost the airline since it relied on the aircraft for its European route network. 

Flybe

Flybe was an independent regional airline in the UK that ceased operations in March 2020 due to the pandemic, as the New York Times reported. The airline had served the furthest and most obscure reaches of the British isle, especially cities that had been shunned by the country's larger carriers. 

A group of companies including Virgin Atlantic Airways, Stobart Group, and Cyrus Capital had purchased the airline in 2019, the Times reported, but that couldn't keep the airline from going under.

Germanwings

Germanwings was one of the Lufthansa Group's low-cost carriers that ceased operations in April 2020 due to the pandemic, as Reuters reported. The Lufthansa Group started these carriers as a way of competing with the likes of Ryanair and EasyJet, which had offered incredibly low fares for flights across the continent. 

The airline had suffered a massive public relations disaster when a co-pilot committed suicide by crashing a plane during a scheduled flight from Spain to Germany in 2015, killing all on board.

Level

Level was a low-cost airline that ceased operations in June and July 2020. The carrier was initially started by the International Airlines Group to rival the likes of Norwegian and Wow Air on transatlantic and intra-European routes.

Flights were operated from Barcelona and Paris to cities across Europe and across the Atlantic to the Americas.  Both the European and the transatlantic divisions of the airline ceased operations due to the pandemic, as FlightGlobal reported.  

NokScoot

NokScoot was a Thai airline that ceased operations in June 2020, as the Bangkok Post reported, citing the effects of the pandemic. The six-year-old airline was the result of a partnership between Scoot and Nok Airlines.

LIAT

LIAT was a Caribbean regional airline that ceased operations in July 2020 due to the pandemic after connecting the region's islands for years, the Caymanian Times reported.
