@ZodiaK @Sa7rawy with Ethiopian Airlines the only airline scheduled to fly to the new Berbera airport and Ethiopian first arriving in June 2nd 2022, I checked Google Flights and what I saw is if you leave London Heathrow on June 1st evening to go to Somaliland using Ethiopian Airlines:
Arriving at Hargeisa June 2nd costs around £542
Arriving at Berbera June 2nd costs around £582
Arriving at Jigjiga June 2nd costs £479
These prices can change. If someone wanted to go to Somaliland via Jigjiga how much does it cost to travel by car plus what charges do you have to pay at the land border
