In the air

Qantas - - Onq -

Mo­bile phones and elec­tronic equip­ment: All trans­mit­ting elec­tronic de­vices, in­clud­ing mo­bile phones, tablets and lap­top com­put­ers, must be switched to flight mode* prior to de­par­ture. Smaller de­vices such as mo­bile phones, e-read­ers, elec­tronic games, MP3 play­ers, iPads and other small tablets may be held in your hands or stowed in a seat pocket. Un­less other­wise di­rected by the cap­tain, these de­vices may re­main switched on and used in flight mode dur­ing take-off, cruise and land­ing. Larger elec­tronic equip­ment such as lap­top com­put­ers may only be used from when the air­craft seat­belt sign is ex­tin­guished af­ter take-off un­til the top of des­cent. Af­ter land­ing, the cabin crew will ad­vise when flight mode may be switched off.

Headsets: Do not use a per­sonal sin­gle-pin au­dio head­set in the Qan­tas in­flight en­ter­tain­ment sys­tem un­less it is sup­ported by a two-pin air­line head­set adap­tor. Per­sonal headsets that con­nect via a cable to a hand­held de­vice can be used at any time from board­ing un­til ar­rival. Headsets and other de­vices that con­nect via Blue­tooth must be switched off for take-off and land­ing but can be used dur­ing cruise. *Flight mode en­ables you to op­er­ate the ba­sic func­tions of your mo­bile phone or per­sonal elec­tronic de­vice while its trans­mit­ting func­tion is switched off, mean­ing you can­not make phone calls or send an SMS.

Your in­flight health: When fly­ing, pas­sen­gers can be seated and in­ac­tive for long pe­ri­ods of time. The en­vi­ron­ment can be low in hu­mid­ity and the cabin pres­sure equiv­a­lent to an al­ti­tude of 2440 me­tres above sea level. The fol­low­ing advice helps you stay healthy dur­ing your jour­ney.

The im­por­tance of in­flight blood cir­cu­la­tion

and mus­cle re­lax­ation: When walk­ing, the leg mus­cle ac­tion helps re­turn ve­nous blood to the heart. Sit­ting in the same po­si­tion for a long pe­riod of time can slow this process and, in some peo­ple, leads to swelling in the feet. Some stud­ies have shown that im­mo­bil­ity as­so­ci­ated with travel of longer than four hours (by air, car or rail) can also lead to an in­creased risk of deep vein throm­bo­sis (DVT), or clot­ting in the legs. Per­sonal fac­tors that in­crease the risk of DVT in­clude: ◖ Age over 40 years ◖ Per­sonal or fam­ily his­tory of DVT or pul­monary em­bo­lus ◖ Re­cent surgery or in­jury, es­pe­cially to the lower limbs, pelvis or ab­domen ◖ Can­cer ◖ In­her­ited or other blood dis­or­ders lead­ing to clot­ting ten­dency ◖ Preg­nancy ◖ Oe­stro­gen ther­apy (oral con­tra­cep­tive pill or hor­mone re­place­ment ther­apy). There are a num­ber of ways to help re­duce the

pos­si­bil­ity of DVT, in­clud­ing the fol­low­ing: ◖ Avoid leg-cross­ing while seated ◖ En­sure ad­e­quate hy­dra­tion ◖ Min­imise al­co­hol and caf­feine in­take be­fore

and dur­ing your flight ◖ Wear com­fort­able, loose-fit­ting clothes ◖ Dur­ing your flight, move your legs and feet for three to four min­utes per hour while seated and move about the cabin oc­ca­sion­ally ◖ Do the light ex­er­cises we rec­om­mend here (see above) and through the in­flight en­ter­tain­ment sys­tem.

If you have con­cerns about your health and fly­ing, or you feel that you may be at risk of DVT, Qan­tas rec­om­mends that you talk to your doc­tor be­fore trav­el­ling. Ad­di­tional mea­sures such as well-fit­ted com­pres­sion stock­ings or anti-clot­ting med­i­ca­tion may be rec­om­mended for high-risk in­di­vid­u­als.

Jet lag: Un­like other forms of trans­port, air travel al­lows for rapid move­ment across many time zones, which can dis­rupt the body’s bi­o­log­i­cal clock. This is com­monly known as jet lag. This dis­rup­tion can af­fect var­i­ous body rhythms such as the sleep-wake cy­cle and the di­ges­tive sys­tem, lead­ing to symp­toms such as tired­ness and lack of en­ergy and ap­petite. In gen­eral, the more time zones crossed, the more dis­rup­tion of the body clock and the more symp­toms ex­pe­ri­enced af­ter the jour­ney. We rec­om­mend the fol­low­ing to min­imise the ef­fects of jet lag. Be­fore your flight: ◖ Get a good night’s rest Dur­ing your flight: ◖ Eat light meals ◖ Wear loose, com­fort­able cloth­ing and sleep

when you can ◖ Stay hy­drated – drink plenty of wa­ter and

avoid ex­cess tea, cof­fee and al­co­hol At your des­ti­na­tion: ◖ If pos­si­ble, give your­self a day or two af­ter

ar­rival to ad­just to the new time zone ◖ Go out in the day­light and do some light

ex­er­cise ◖ Try to eat meals and do other so­cial ac­tiv­i­ties at ap­pro­pri­ate des­ti­na­tion times to ad­just to the new time zone

Cabin hu­mid­ity and hy­dra­tion: Hu­mid­ity lev­els of less than 25 per cent are com­mon in the cabin, as the out­side air that sup­plies the cabin is very dry. The low hu­mid­ity can cause dry­ing of the sur­faces of the nose, throat and eyes and it can ir­ri­tate con­tact lenses. If nor­mal fluid in­take is main­tained dur­ing the flight, de­hy­dra­tion will not oc­cur. We rec­om­mend: ◖ Drink wa­ter and juices fre­quently dur­ing

the flight ◖ Drink cof­fee, tea and al­co­hol in mod­er­a­tion ◖ Re­move con­tact lenses and wear glasses

if your eyes are ir­ri­tated ◖ Use a skin mois­turiser to re­fresh the skin

Cabin pres­suri­sa­tion: Dur­ing flight, air­craft cabin pres­sure is main­tained to a suf­fi­cient den­sity for your com­fort and health. As the air­craft climbs, the cabin may reach the same air pres­sure as at an el­e­va­tion of 2440 me­tres above sea level. Cabin pres­sure does not pose a prob­lem for most pas­sen­gers. How­ever, if you suf­fer from ob­struc­tive pul­monary dis­eases, anaemias or cer­tain car­dio­vas­cu­lar con­di­tions, you could ex­pe­ri­ence dis­com­fort at these al­ti­tudes. These pas­sen­gers should seek med­i­cal advice be­fore fly­ing, as some may re­quire sup­ple­men­tary oxy­gen. Qan­tas can ar­range this but re­quires at least seven days’ no­tice be­fore trav­el­ling. The rate of change in cabin pres­sure dur­ing climb and des­cent is also care­fully main­tained and does not usu­ally cause dis­com­fort. How­ever, chil­dren and in­fants, and adults who have si­nus or nasal con­ges­tion, may ex­pe­ri­ence some dis­com­fort be­cause of pres­sure changes dur­ing climb and par­tic­u­larly des­cent. Those suf­fer­ing from nasal or si­nus con­ges­tion be­cause of a cold or al­ler­gies may need to de­lay travel. The fol­low­ing advice may as­sist: ◖ To “clear” your ears, try swal­low­ing, yawn­ing or pinch­ing your nose closed and gen­tly blow­ing against it. These ac­tions help open the Eus­tachian tubes, equal­is­ing pres­sure be­tween the mid­dle ear cham­ber and throat. ◖ If fly­ing with an in­fant, feed or give your baby a dummy dur­ing des­cent. Suck­ing and swal­low­ing help equalise pres­sure in an in­fant’s ears. Give chil­dren some­thing to drink or chew dur­ing des­cent. ◖ Con­sider us­ing med­i­ca­tion such as nasal sprays, de­con­ges­tants and an­ti­his­tamines 30 min­utes prior to des­cent to help open up your ear and si­nus pas­sages.

Mo­tion sick­ness: Air travel, es­pe­cially if tur­bu­lence is ex­pe­ri­enced, can cause mo­tion sick­ness, as it leads to a con­flict be­tween the body’s sense of vi­sion and its sense of equi­lib­rium. Main­tain­ing good vis­ual cues (keep­ing your eyes fixed on a non-mov­ing ob­ject) helps pre­vent mo­tion sick­ness. When the weather is clear, you should look out at the ground, sea or hori­zon. If the hori­zon can’t be seen, clos­ing your eyes and keep­ing your head move­ments to a min­i­mum will help. While over-the-counter med­i­ca­tions are avail­able, we rec­om­mend you con­sult your doc­tor about the ap­pro­pri­ate med­i­ca­tions. More in­for­ma­tion can be found: ◖ At qan­­ing/intheair/

yourhealth­in­flight ◖ Through the on­board en­ter­tain­ment sys­tem ◖ On our in­for­ma­tion leaflet avail­able from

Qan­tas or your travel agent

Smok­ing: Gov­ern­ment reg­u­la­tions pro­hibit smok­ing on all flights op­er­ated by Aus­tralian­reg­is­tered air­craft. The use and charg­ing of all e-cig­a­rettes and other per­sonal va­por­is­ers are not per­mit­ted on board an air­craft. There are smoke de­tec­tors in all toilets and penal­ties for reg­u­la­tion breaches.

Trav­el­ling with chil­dren: Please ask cabin crew for help if re­quired. Baby food and nap­pies (di­a­pers) are avail­able on most flights, while some wash­rooms are fit­ted with baby change ta­bles. Please dis­pose of nap­pies etc. in the waste bins.
