A 47-year-old man and 54-year-old woman from Crawley are being questioned over multiple drone sightings that brought Gatwick Airport to a standstill.
Flights were grounded for more than 36 hours when drones were first spotted close to the runway on Wednesday night.
The airport has since reopened and flights were operating on schedule, but there were still long queues and some knock-on delays, a spokesman said.
Police are searching a house in Crawley and the pair remain in custody.
They were arrested on Friday evening and were being questioned on suspicion of disrupting civil aviation "to endanger or likely to endanger safety of operations or persons", Sussex Police said.

About 1,000 aircraft were either cancelled or diverted and about 140,000 passengers disrupted during three days of disruption.
The airport was forced to shut its runway for spells on Wednesday and Friday and for all of Thursday.
The drones were first spotted at about 21:00 GMT on Wednesday.
Every time the airport sought to reopen the runway on Thursday, the drones returned.
I expect there will be more direct action in future, to avoid such widespread disruption.
It just goes to show how easy it is to cause major disruption with such simple devices these days.
