could i take advantage of the US DOLLAR being weak atm, and buy...

[noonar]

...flights to america in dollars, with a US airline, to get a relatively cheap fare???

not should how to do this, or even if this idea could work.

what do you thnk??

I don't think you can.

Because the dollar is weak, you get more dollars to the pound not less so you're better to pay in pounds, I think.
ie: $200 now equals £100 pounds, whereas $180 used to equal £100.

but surely if the fare was $600, it would only cost me £300-ish, so would be relatively cheaper than the same fare a few years ago

scootergrrl, am pretty sure its the other way round.
