Narrative:
On ZDV frequency, we heard other aircraft being given horizontal and vertical vectors. We were not aware of the act that we were the 'problem'. We had climbed to FL290 then FL310 with ZLC. We had filed for FL330 but were not concerned with not being given FL330. The ride at FL310 was good. Our flight continued to dfw uneventfully. We continued dfw-lga, arriving lga, the captain was advised to call den ARTCC. Apparently the handoff from slc to den ARTCC was not well coordinated. At no time did we lose radio with ARTCC and we believe we were at the assigned altitude throughout our flight. We were never aware of an altitude conflict between our aircraft and other air carriers near alamosa, co.

Title: FLT CREW OF ACR LGT SUSPECTS THEY WERE LEFT AT A WESTBOUND ALT ON AN EASTBOUND FLT AND THAT THE ALT WAS NOT COORDINATED WITH THE NEXT ARTCC SECTOR.
Narrative: ON ZDV FREQ, WE HEARD OTHER ACFT BEING GIVEN HORIZONTAL AND VERTICAL VECTORS. WE WERE NOT AWARE OF THE ACT THAT WE WERE THE 'PROBLEM'. WE HAD CLIMBED TO FL290 THEN FL310 WITH ZLC. WE HAD FILED FOR FL330 BUT WERE NOT CONCERNED WITH NOT BEING GIVEN FL330. THE RIDE AT FL310 WAS GOOD. OUR FLT CONTINUED TO DFW UNEVENTFULLY. WE CONTINUED DFW-LGA, ARRIVING LGA, THE CAPT WAS ADVISED TO CALL DEN ARTCC. APPARENTLY THE HANDOFF FROM SLC TO DEN ARTCC WAS NOT WELL COORDINATED. AT NO TIME DID WE LOSE RADIO WITH ARTCC AND WE BELIEVE WE WERE AT THE ASSIGNED ALT THROUGHOUT OUR FLT. WE WERE NEVER AWARE OF AN ALT CONFLICT BETWEEN OUR ACFT AND OTHER AIR CARRIERS NEAR ALAMOSA, CO.
