The peak year was 2000. The Pope visited Israel and many came with him.
There were 9,301,607 passengers in 2000.
On Sep 2000 the Intifada began and the numbers started to drop.
In 2001 there were 7,878,306 passengers and in 2002 (the worse year) there were only 6,853,104 passengers.
2003 suppose to be a better year.
The numbers are from TLV
web site. You can find it here: http://www.ben-gurion-airport.co.il/english/index.htm
Unfortunately the English section of the web site has much less statistic information than the Hebrew section.
You can try to understand some numbers from the Hebrew section (it’s not too difficult). The first table is at http://www.ben-gurion-airport.co.il/hebrew/report/report1.htm
At the bottom of each page, click on the Blue aircraft to jump to the next table.
As other said, the decision about T3
opening date has nothing to do with pax number.
