Hi Many thanks for your replies guys, double checked the DFW-CUN and this is business not first I assumed it was first as there is only two classes on this flight. I previously been informed of the I-T-I program and when speaking to others some people said that you had to collect your bags and some said the opposite thankfully im more positive now that this is the case.

Ive been doing some research on the BA193 flight up until 30 March this departs at 10.55 rather than 11.55 and arrives somewhat earlier that 15.55 but from then on it departs at the 11.55 time why I cant answer? Also looking at history of the aa1211 flight that also is delayed on occasions.Over last 15 days this has been delayed on average 25 mins so hopefully will be the case for us.

im hopefull BA wouldnt sell this as a connecting flight if they didnt believe that this was connectable. Hopefully there will be agents there to help us if we arrive late or in long immigration ques. Have seen Delta agents at JFK terminal hurrying passengers in checkin ques who were on connecting flights hopefully this is the case at DFW. Below is the link I was once given regarding the I-T-I
