Address: 110092

Hi, I was booked two ticket for Lucknow from flight 6E 522 in morning and scheduled departure time was 10.05 AM.It's an emergency journy due to death of close family member. My booking reference no was R4VZ3V. I reached at airport just 09.32 AM. Ur staff denied me to issuing boarding pass due to late entry. I'm just requested to its urgency for me even clearing him regarding death of family member. But they are very rude and not cooperating with us. Finally I was not attend funeral of my close buddy. Just due to rude and unethical behavior o[censored]r staff. Tell me whats solution for me.
