If you really want to have your route go across the pacific, there is a free application available that will provide you with results similar to this
The application uses google maps and because it is freeware it takes some time to figure out how to use it. It is also a little cumbersome and does not look or act nearly as sophisticated as the Travel Route Animator in MEP. But if you really want to fly across the pacific this is the only way I know how to do it short of purchasing a seperate travel route animator. It is available at http://sourceforge.net/projects/routegen/files/routegen/1.6/routegen-win32-1.6.exe/download
If enough people would like me to create a video tutorial on how to use this product, send me a personal message and if there is enough interest I will do it and hopefully save you some time with the ins and outs of this product.
