The 1997 Asian Financial Crisis hurt Delta Air Lines's operation, and international travel decreased even further due to complaints about treatment at the immigration facility in Portland, leading it to be nicknamed "DePortland". The combination of these factors caused Delta Air Lines to discontinue what was then the last direct flight from Portland to Tokyo and from Portland to Nagoya in March 2001. This change brought local media scrutiny. This then combined with the resulting congressional pressure, caused the officials in charge of the immigration facility to address the problems.
