Should you fly while fasting? The honest answer.

The question behind the question

When a family asks whether it should travel during Ramadan, it is rarely asking about aircraft. It is asking whether the month will survive the journey: whether the grandmother will manage, whether the children will be miserable, whether the fast will be kept or broken and made up, and whether the whole thing will feel like a holiday interrupted by a religious obligation instead of a month kept properly in a comfortable place. Those are fair questions and they have practical answers, most of which come down to when the aircraft leaves.

The religious side we leave where it belongs. Islam makes provision for the traveller and for those who cannot fast, and the conditions attaching to that provision, and whether taking it is preferable in a given case, differ between schools and between scholars. We do not rule and we do not advise. We ask every family to settle it with their own scholar before booking, because the answer changes the itinerary: a family that intends to fast throughout needs a different flight from a family that intends to take the concession and make the days up later.

The arithmetic of flying east

Thailand is four hours ahead of Riyadh, Kuwait, Manama and Doha, and three hours ahead of Dubai, Abu Dhabi and Muscat. Flying time from the Gulf runs roughly six to seven hours. Flying east therefore shortens the remaining day: the aircraft chases the sunset and loses. That is a genuinely useful fact for a fasting traveller and almost nobody applies it when they book.

Worked through, a departure from Riyadh at nine in the morning lands in Bangkok around half past seven in the evening local time, which in the current part of the cycle is after maghrib. The family fasts through the flight and breaks it on arrival, or shortly before landing. A departure taken in the late evening, after iftar and after taraweeh, arrives in the Bangkok morning and puts the whole of the next fast on the ground with a bed available. The one to avoid is the mid afternoon departure, which lands somewhere around midnight, wrecks the first suhoor and leaves the family fasting on the first day with no sleep behind them.

In the air

The Gulf carriers plan for Ramadan and most will serve an iftar tray at the correct moment for the aircraft's position, with dates provided. The arrangement differs by airline, by cabin and by route, and it is worth confirming when the ticket is issued rather than discovering it at thirty eight thousand feet. Where the family is in a private cabin or on a chartered aircraft, the catering brief is yours to write, and the same rules apply as on the ground: dates and water first, light before heavy, and the timing calculated for the position rather than the departure city.

Cabin air is dry and the fast is harder than the same hours on the ground. The measures that help are unglamorous: hydrate properly at suhoor rather than in the last ten minutes before fajr, keep the cabin cool, avoid salt on the pre dawn tray, and sleep rather than watch films. Prayer on board is a matter for the traveller and their own scholar; practically, most of the aircraft used on this route have space near a galley or a door where a person can pray without obstructing a crew member, and the cabin crew on Gulf carriers are entirely accustomed to the request.

Jet lag against fasting hours

Three or four hours is a mild time change, which is one of the reasons this route suits Gulf families so well. In Ramadan, though, the small shift lands in exactly the wrong place. Suhoor in Bangkok at half past four in the morning is half past midnight by a Riyadh body clock, and iftar at six in the evening is the middle of a Gulf afternoon. For the first two days the family is effectively eating at the wrong times twice a day, and the tiredness that follows is usually blamed on the fast rather than on the clock.

It resolves quickly if the first day is planned rather than filled. Nothing scheduled on arrival day, a proper sleep in a dark room, the first iftar arranged before the family lands so that nobody has to make a decision, and a late start on day two. By the third day the household has settled into local time and the month proceeds normally. Families that programme meetings or shopping into the arrival day pay for it for a week.

Children, elderly travellers and anyone unwell

Children who are fasting, or fasting part of the day, do better on the late evening departure that lets them sleep on the aircraft and wake in Bangkok. Elderly parents do better on the same flight for different reasons: less time upright, a shorter awake period, and a hotel bed available soon after landing. Wheelchair assistance at Suvarnabhumi is reliable but must be booked with the airline in advance, and the walk from a remote gate to immigration is long enough to matter to someone who has fasted through a flight.

Anyone travelling for treatment, anyone on a medication schedule and anyone recently discharged should have the fasting question settled with their treating doctor as well as their scholar, in advance, and should carry medication in the cabin with its documentation. We do not advise on any of that. What we do is put the hospital, the pharmacy and the doctor's contact details in the car folder before the family lands, and keep the arrival day empty so that nothing has to be rearranged around a person who is tired.

Landing

Entry procedure is unaffected by the month. The Thailand Digital Arrival Card must be filed online within seventy two hours of arrival at tdac.immigration.go.th, and airlines increasingly check it before boarding, so file it before leaving home rather than in a queue. The visa exemption for GCC nationals currently runs to sixty days, with an approved reduction to thirty days pending publication in the Royal Gazette, so confirm the allowance that applies on your travel dates with the Royal Thai Embassy in your country before booking. Suvarnabhumi has prayer rooms, and fast track immigration is worth arranging for a large party arriving at a busy hour.

The last piece is the one families forget. Whatever hour you land, the first meal of the month in Thailand should already be arranged: the suite stocked, the suhoor menu agreed, the iftar timing given to the hotel, and the car standing. Arriving at ten at night and then trying to organise a four in the morning breakfast is how a good month starts badly, and it is entirely avoidable with a week's notice.

Whether to fast while travelling, and what any concession requires of you afterwards, is a question of religious law for your own scholar, and any question of fasting alongside medication or treatment is one for your treating doctor. Confirm Ramadan dates and prayer timings with your own Islamic authority at home and with the Office of the Chularatchamontri in Thailand, confirm in flight Ramadan catering with your airline when the ticket is issued, and confirm entry requirements and the current visa exemption period with the Royal Thai Embassy in your country before booking.
