Narrative:

After a partial crew swap in dfw (swapped out first officer's) and an exhausting attempt at obtaining our IFR flight plan to georgetown, grand caymen (mwcr), we finally decided to go and phone file another flight plan (international). As our passenger set aboard the aircraft, we finally corrected the commercial fir crossing boundary eet's and filed the plan with FSS. After all was said and done, we took over a 1 hour delay and finally got airborne at XA07. We were slightly ahead of our fir crossing, but merida had us in radar contact. While chatting with my new first officer (whom I gave the leg to), I was checking off waypoints and doing position reports when necessary. Upon receiving 'radar contact' from merida, I ceased the position reports and planned on resuming then approaching cenamer control. Then we heard military B747 check on frequency. An air carrier jet crew contacted them and asked them to change frequency to chat. We listened in and before I knew it we were already inside cenamer control airspace and were contacted by another crew with a relay to change frequency. Apparently there was no conflict, but I did not give a call 10 mins prior to entering their airspace. It was then that I realized we were being complacent and began focusing on the task at hand. The lack of smooth flow prior to our departure apparently took its toll on me mentally and it took this event to show it to me.

Narrative: AFTER A PARTIAL CREW SWAP IN DFW (SWAPPED OUT FO'S) AND AN EXHAUSTING ATTEMPT AT OBTAINING OUR IFR FLT PLAN TO GEORGETOWN, GRAND CAYMEN (MWCR), WE FINALLY DECIDED TO GO AND PHONE FILE ANOTHER FLT PLAN (INTL). AS OUR PAX SET ABOARD THE ACFT, WE FINALLY CORRECTED THE COMMERCIAL FIR XING BOUNDARY EET'S AND FILED THE PLAN WITH FSS. AFTER ALL WAS SAID AND DONE, WE TOOK OVER A 1 HR DELAY AND FINALLY GOT AIRBORNE AT XA07. WE WERE SLIGHTLY AHEAD OF OUR FIR XING, BUT MERIDA HAD US IN RADAR CONTACT. WHILE CHATTING WITH MY NEW FO (WHOM I GAVE THE LEG TO), I WAS CHKING OFF WAYPOINTS AND DOING POS RPTS WHEN NECESSARY. UPON RECEIVING 'RADAR CONTACT' FROM MERIDA, I CEASED THE POS RPTS AND PLANNED ON RESUMING THEN APCHING CENAMER CTL. THEN WE HEARD MIL B747 CHK ON FREQ. AN ACR JET CREW CONTACTED THEM AND ASKED THEM TO CHANGE FREQ TO CHAT. WE LISTENED IN AND BEFORE I KNEW IT WE WERE ALREADY INSIDE CENAMER CTL AIRSPACE AND WERE CONTACTED BY ANOTHER CREW WITH A RELAY TO CHANGE FREQ. APPARENTLY THERE WAS NO CONFLICT, BUT I DID NOT GIVE A CALL 10 MINS PRIOR TO ENTERING THEIR AIRSPACE. IT WAS THEN THAT I REALIZED WE WERE BEING COMPLACENT AND BEGAN FOCUSING ON THE TASK AT HAND. THE LACK OF SMOOTH FLOW PRIOR TO OUR DEP APPARENTLY TOOK ITS TOLL ON ME MENTALLY AND IT TOOK THIS EVENT TO SHOW IT TO ME.
