Best Answer
Ads:
- Quick to do
- No need to travel anywhere (to book the tickets)
- Real time process (if you book a seat, it will automatically update it so no one else can take that seat. If you used an agent that did not use computers, they would need to call other agents saying "Seat X has been taken")
- Could be cheaper
- Can access more information and find other deals online
- Websites can compare different flight prices and details
Disads:
- Need internet and PC experience
- Might need a credit card or some other form of payment
- Viruses/Trojans online that steal your information
- If the website is down, you won't be able to book it online
