The 777-200 is one of the very few airplanes that beside the 747 looks great or at least good in almost every scheme.
Asiana, Saudi Arabian, Lauda Air, KLM, Korean Air, United and American´s 772s all look great. Vietnam, BA
, China Southern and CX
The only 777-200s I really don´t like are Air China´s, Egyptair´s, Aeroflot´s and the Air Europe duo that´s history now (with the exception the 777s days in these airlines are numbered anyway).
Air France´s, Alitalia´s, Thai´s, Emirates´, Continental´s, Kuwait´s and SIA´s 777s are so-so for me, their schemes are certainly not tailormade for this aircraft. AFs livery on the 777-300 emphasizes that clearly. Its the opposite of a good-looker. Long cheatlines don´t look good on the unbalanced design of the 773 as well, that makes Thai´s and SIAs 773s ugly.
