Between the jet fuel crisis and the regular challenges that have been plaguing many smaller airlines over the last year, many have been forced to shut down since the start of 2026.
Issued by the aviation regulatory authority in a given country, the Air Operator’s Certificate (AOC) is granted once the airline proves that it has the aircraft, staff, safety systems and financial resources to launch and stay operational.
Lack of the latter is one of the most common reasons for an airline to get its AOC revoked; examples of carriers that have had this happen in recent months include Estonia’s SmartLynx Airlines, Austria’s Mali Air, Malta’s HiFly, Swedish charter carrier H-Bird as well as Houston-based charter carrier Starflite Aviation.
Pen-Avia charter airline no longer has active AOC: report
As is now being reported by Swiss airlines news site ch-aviation, British charter airline Pen-Avia now also no longer has an active AOC license. The carrier had previously retired its only aircraft, a Gulfstream Aerospace GVII-G60 with room for up to 19 passengers, in November 2025 but has kept the possibility of restarting operations on the table.
On its website, Pen-Avia advertises itself as a charter airline that can offer “flights [that] can be coordinated to a wide array of airports” and get travelers “closer to your final destination than is possible with a commercial airline.”

The airline is based in Hertfordshire and operated bases out of London Luton Airport (LTN). It has not provided comment on its current financial state. In November 2025, potential passengers who tried to contact the airline received an automated response saying that they were not running any charter flights.
Without an AOC, it is now unable to legally run or market flights to passengers.

What happens when an airline loses its AOC, operating license
Other charter airlines which lost their AOCs struggled with similar problems of making up for the high cost of aviation with enough high-earning clients willing to pay for charter flights.
These are the airlines that shut down in 2026:
- Magnicharters: While not yet fully shut down, Mexican low-cost airline Magnicharters canceled all flights until May 2026 in a shutdown that left thousands stranded.
- Starflite Aviation: Houston-based Starflite Aviation had its AOC license revoked in March 2026, amid FAA claims that owners falsified pilot training records to bypass safety audits.
- AlpAvia: Slovenian charter airline AlpAvia also shut down in March 2026 over financial problems.
- H-Bird: Charter airline H-Bird was declared bankrupt by a Swedish judge after losing its operating license at the end of 2025.
New York-based charter airline Tailwind Air initially tried to launch by running short flights between New York, Boston, and several other East Coast cities but ended up struggling to bring in passengers and ultimately having to file for Chapter 11 protection in January 2026.

In January 2026, fellow British carrier Ecojet entered voluntary liquidation, or the British equivalent of Chapter 7 bankruptcy, after green investor Dale Vince’s initial business plan of converting kerosene engines on old aircraft into hydrogen-electric ones for the world’s first “eco-friendly airline” started bleeding through money.
