Only if your previous statement has been fully paid off. I learnt this the hard way, couple of years ago.Personally, I use the Halifax travel card as My travel credit card. The forex rates, free cash withdrawals and interest free, if you pay the amount you taken out on the same day makes it worth it.
Had £1k on my Clarity statement, balance transfer so was 0% interest so no rush to pay it off. Went on holiday, withdraw £250 as soon as touched down at airport. Paid £250 to my Clarity same day from my current account, did same few more times so £1k total cash withdrawn, each time paying the same amount to the card, thinking it would pay off the cash withdrawal instantly so I will pay 0 interest... How wrong I was when I saw next month's statement.
Turns out that £1k had actually paid off the £1k interest free balance I had on the previous statement... And I now had £1k of cash withdrawals on my new statement with the crazy interest to go with it...
Completely my mistake but I did call up Halifax and they were very understanding, must catch a lot of others out, as they straight away offered to waive the interest charges for that month.
