For example, most aggregators do not sell tickets from China to the United States (presumably to avoid the risk of going against the restrictions and having to pay for the flight of a passenger for out of the country).
Kwa mfano, wauzaji hawauzi tiketi kutoka Uchina hadi Marekani (hiyo ni kwa sababu ya kuepuka kukiuka vikwazo na kushindwa kupata ndege ya abiria ya kutoka)
