The 4 Things That Go Wrong
- Luggage doesn't arrive at T3 with you (cross-PNR)
- Security re-screen takes 30+ min on heavy days
- Gate change at last minute, far walk
- Immigration queue 60-90 min on heavy arrival days
Where to Wait if 4+ Hrs Layover
T3 has the only proper international-class lounges (PriorityPass + Plaza Premium). T1 is functional. T2 has limited dining. For long layovers, leave airport (Aerocity hotel day-room or Lodhi Garden) — 30 min round-trip.
Late-Night Protocols
Post-midnight shuttle frequency drops to 30 min. Last shuttle 4 AM, first 4:30 AM. If you arrive at odd hour, plan accordingly.
