Basic example Airport traffic

[Joaquín Silva]

Hi, I new using Neo4j so I began with a very basic example.I have a table with  this info:

Bill_To_Adress_provided	Arriving_Airport	Departing_Airport
Address 1234	COR	BUE
⁞	⁞	⁞

So I did a graph with 3 nodes: Adress, Arrive, Depart and the relationship between them. This is the query:

CREATE CONSTRAINT ON (a:Address) ASSERT a.id IS UNIQUE;

CREATE CONSTRAINT ON (b:Arrive) ASSERT b.id IS UNIQUE;

CREATE CONSTRAINT ON (c:Depart) ASSERT c.id IS UNIQUE;

USING PERIODIC COMMIT

LOAD CSV WITH HEADERS FROM

"file:f:/address/to/the/table.csv" as transactions 

FIELDTERMINATOR ';'

MERGE (address:Address {id: transactions.Bill_To_Adress_provided})

MERGE (arrive:Arrive {id: transactions.Arriving_Airport})

MERGE (depart:Depart {id: transactions.Departing_Airport})

CREATE (address)-[r:FROM]->(arrive)

CREATE (depart)-[s:TO]->(address)

;

But now I want to merge Arriving_Airport with Departing_Airport in a node call Airport. How can I do that?.
