I had a dreadful experience at Delhi Airport due to the dirtiness, disarray, delays, and staff mistreatment. From the second I arrived, the air terminal was chaotic and untidy, and there were long deferrals for security and registration. The staff were unhelpful and offhand, frequently discourteous and aloof when I requested help. This experience was very disagreeable, and I would suggest you avoid Delhi Airport because of its absence of tidiness, association, postponements, and staff badgering.
