ok, so how much $ to fly from texas, to ireland w/ my friend?not round trip. and in the winter?

Answer 1

There are a lot of "If" involved here. If, you go buy a Ticket and expect to leave that day it expensive. If, you buy a ticket to leave 3 months down the road it be cheaper. If, you leave during high traffic times (others wanting to fly, say 8 a.m.) it more expensive than "IF" you leave at 1 a.m.
So, I say $900 one way on Southwestern Airlines, IF, they have flights to Ireland.

Answer 2

OK, let's keep this simple.
Go to www.bestchoicetravels.com and choose 'Flights' from the drop down menu.
Choose 'Farebuzz' and enter the specific information it asked about your trip. The key word here is specific. There is no "winter" in the available choices.
Enjoy the rates.
