Contrary to replies no. 1 and 2 which run counter to the validity and spirit of the original question - some LCCs have indeed pitched in to help in this very real tragedy.
Virgin Express is operating a 30-min special flight over Belgium on 8 Jan 2005 to raise funds for the Tsunami Relief Fund and ticket are priced at Euro 49. Subject to demand, more than one flight could be operated.
Virgin Blue has flown aid workers from Australia to Phuket.
Tiger Airways has also provided complimentary transportation from Singapore to Phuket for relief workers and supplies. It has also provided its passenger manifests to the Singapore government to help track people reported missing.
Nok Air offered free flights to Phuket for doctors.
This tragedy (and mind you, it is not only an Asian tragedy as countries such as Sweden, France, UK and Germany along with many others around the world mourn significant numbers of their own) has brought out the true spirit of giving in the darkest and final days of 2004, and these include:
Air Canada which operated two A343 flights to Jakarta.
Qatar Airways which helped evacuate stricken tourists from the Maldives.
Thai Airways International which transported relief teams and supplies to Phuket and evacuated injured victims and stranded visitors to Bangkok.
Bangkok Airways which transported injured victims from Phuket to Bangkok.
Singapore Airlines which flew volunteer doctors from Singapore to Sri Lanka, donated S$300,000 to Tsunami Relief Funds. SIA and SIA Cargo are flying relief supplies from around the world to the stricken countries.
Malaysia Airlines is transporting relief goods from around the world to the affected countries and has pledged US$52,632 in donations.
Qantas Airways has dedicated an aircraft to relief efforts in Thailand and Sri Lanka (no mention of what aircraft type).
Jet Airways, Air Sahara and Indian Airlines are ferrying relief supplies to the Nicobar and Andaman Islands.
Finnair helped evacuate citizens from Scandinavian countries and has transported relief supplies, aid workers and a field hospital to Phuket.
SAS is making a collection onboard its flights/check-in counters/hotels and matching such collections over a two-week period. This money will be donated to the Save The Children fund.
Dragonair has transported government relief supplies from HKG
's Change For Good will donate its entire collection in Jan 2005 to UNICEF to fund relief efforts in tsunami-struck countries.
China Southern Airlines has taken a B744F out of line service to operate flights to Sri Lanka.
Emirates has operated humanitarian relief flights to transport supplies to Sri Lanka, Maldives, India, Bangkok and Kuala Lumpur.
And last but not least, Cathay Pacific (as mentioned earlier in this post) has been quick to react and has made a HK1 million donation to start the CX SE
Asia Disaster Relief Fund rolling. It will match staff contributions during the fund's first month. CX
has also donated blankets and medical supplies and provided transported such supplies to stricken countries.
These are by no means the only airlines which have been generous in contributing both cash and services - and I hope to learn of many more through the great discussion.
Beyond the immediate needs, survivors of the disaster will need further support to re-build their lives and livelihood (and children have special needs and need your special attention). So where you find yourself as an airline passenger being asked for a little extra, give generously.
