Fouled up wifi connection

Today I traveled on Southwest Airlines and connected to its on plane wifi from my new iPad. I spent little time there after seeing they wanted money.
Now at home I wifi reconnected to our home router and all is well except when I try to connect to two particular forums, it goes to getconnectedsouthwestairlines.com and never connects. Is this anything rhp can help with?
Ps I did a reboot, didn't help.

Try clearing browser cache.

This may help :

It worked!

Thanks!
