Kushok Bakula Rimpochee Airport at Leh sits at 3,256m above sea level, which means your flight lands in air with roughly 35 percent less oxygen than Delhi. Here is the practical 2026 guide to IXL flights, the morning weather window and the acclimatisation reality.

Frequently asked questions
Which airline has the best on-time record for DEL-IXL flights?
IndiGo consistently has the best on-time performance on DEL-IXL based on DGCA monthly data, typically operating 80 to 85 percent of flights on time during summer and around 70 percent in winter. Air India is competitive in summer but more affected by winter cancellations because of crew rostering challenges. The early-morning departures (05:30 to 07:00 from Delhi) have materially better on-time performance than the later slots, because they get into Leh before the afternoon weather window closes.
Is it safe to fly to Leh if I have high blood pressure?
It depends on how well controlled your BP is and your overall cardiovascular health. Well-controlled hypertension on standard medication is generally not a contraindication to Leh travel, but you must consult your physician before booking. People with poorly controlled BP, recent cardiac events, severe pulmonary disease (COPD, severe asthma) or sickle cell disease should avoid high altitude. Carry your regular medications, a written summary of your conditions and your physician's contact for the trip. Sonam Norboo Memorial Hospital in Leh is equipped for hypertensive emergencies.
What is the cheapest month to fly to Leh from Delhi?
March to mid-April typically has the cheapest DEL-IXL fares, often clearing at 4,500 to 6,500 rupees one-way on IndiGo and Air India. October is also reasonably priced (6,000 to 9,000) and has stable weather. The catch with March-April is that many tourist circuits are still closed by snow — Pangong road may not be open until late April, Khardung La is technically open but icy, Nubra access is limited. October is a sweet spot with stable weather, fewer crowds and most circuits still accessible before winter shutdown.
Do I need Diamox to fly to Leh?
Diamox (acetazolamide 125mg twice daily) is recommended for fly-in arrivals at Leh, starting 24 hours before departure and continuing 48 hours after arrival. It is not mandatory and many travellers fly in without it, but it materially reduces AMS incidence and severity. Speak to your GP for a prescription before the trip — it costs roughly 50 to 80 rupees for a strip of 10 tablets. Do not start Diamox for the first time on the morning of the flight without medical advice; if you have sulpha drug allergy you cannot take it.
Can I fly to Leh and immediately drive to Pangong Lake the same day?
Strongly discouraged. Pangong Lake sits at 4,350m and the drive crosses Chang La pass at 5,360m. Driving up another 1,000m on your day of arrival when you have just jumped from sea-level pressure to 3,524m is a leading cause of severe AMS and pulmonary oedema. The minimum safe protocol is 36 to 48 hours of acclimatisation in Leh town before attempting any 4,000m+ destination. Pangong is best visited on day 3 or 4 of your trip, not day 1.
What happens if my Leh flight is cancelled because of weather?
Carriers will rebook you to the next available flight at no extra cost when the cancellation is for weather. In peak season this may be 24 to 48 hours later because flights are sold out. You are entitled to meal and refreshment vouchers under DGCA rules. Hotel accommodation is provided only if the airline requires you to stay overnight at the airport city, not if you are at your home city. For winter travel, build a 2-day buffer either side of your Leh schedule for weather contingency.
How much luggage am I allowed on Delhi to Leh flights?
Standard Indian domestic allowance applies — typically 15 kg checked plus 7 kg cabin on IndiGo and Air India, though some carriers reduce checked to 10 kg specifically on IXL routes in peak summer due to weight restrictions. Cabin allowance is strictly enforced because cabin overhead bin space is at a premium on the smaller A320 in high-altitude conditions. Wear your bulky winter wear rather than packing it. Excess baggage on IXL routes runs 600 to 800 rupees per kilo, which is more than the standard rate.
Are there direct flights from Bangalore or Hyderabad to Leh?
Not as direct services in 2026. All BLR, HYD, MAA and CCU flights to Leh route through Delhi with a connection. IndiGo offers through-ticketing on some itineraries with protected rebooking if the connection is missed. The realistic approach from southern Indian cities is to fly to Delhi the previous evening, overnight at an airport-area hotel and take the morning IXL flight. Direct seasonal services from Bombay (BOM-IXL) do operate in peak summer on IndiGo, typically as a daily service from late May to early September.
