How do I train my 3-year old dog to pee on a pee-pad?

In a month, I will be flying to Arizona from Florida with my 3-year old Chihuahua Terrier mix. Now it is a 4 hour and 45 minute flight. I have been reading up on tips and lessons on flying with dogs in cabin, with you on the floor. Because I can't leave the airport whenever my dog needs to go to the bathroom, I have considered the idea of pee pads. My dog does not usually pee on pads, she goes outside. I want to teach her that its okay to pee on the pad, but don't want her to get used to it because she won't be doing it when we get home. Please any suggestions would be great!

Added (1). Because of all the answers I have been getting, I want to apologize. Obviously it wasn't okay to assume my dog could just forget what I thought her about gong to the bathroom on a pee pad. But because you guys don't know my dog, you can't assume so wouldn't be open to the possibly. And second, if any of you read my actual question and additional information, you would know that I asked for suggestions on how to get her to go to the bathroom if its an actual EMERGENCY.

Bus IC Cards in Japan?

Hi! I'm planning to go to Japan at the end of the year, and want to plan everything out first. I would like to know which kind of IC card to use if I want to get on a bus from Kansai Airport to USJ in Osaka as well as Kyoto. I looked up the cards, and there seem to be so many to choose from. Which card is suitable for travelling by bus in these places.
And if you can, maybe explain how the busses work? Is there english in the signs?
