The headache and blood in your mucus are an uncommon combination. They are probably unrelated. However it is possible that you had a transient rise in blood pressure, resulting in both headache and a broken blood vessel somewhere in your respiratory tract. Put the headache aside for a moment, especially if it has not returned. The most likely problem, with the combination of blood in your sputum and air travel, would be a pulmonary embolus. This is a blood clot in an artery of the lungs. Talk about this with your doctor to see if there are any other reasons to suspect this problem. If not, it might be reasonable to wait a few days for the blood in your mucus to clear up and go away.
Definitely rule out more serious possibilities, though.
I had the same problem a couple of weeks ago but I did not get the inflammation until last Saturday (at least noticably).
Like you, I have clear mucus but small clots/streaks of blood on the back of my throat and I had nausea/fever. I went to the doctor and after examining me (I had ear infection and symptoms of sinus problems), determined I had a Infection of the throat/ears/sinuses. They told me inflamation (inflammation) was the likely cause of the bleeing and prescribed me a back-to-back course of Antibiotics.
I am 35...dont smoke (I smoked as a kid for a while but stopped 20yrs ago) and I am a fitness fanatic, I hardly drink.
That said, these past few days since Saturday the bleeding streaks really havent subsided however there has been improvement in my overall condition (no fever and ear probs subsiding...my sinus areas around my eyes still ache.
The streaking/production of blood is not huge (wouldnt fill a teaspoon) but the small clots (like the tip of an eraser on a pencil) are concerning, despite my Docs' reassurances.
The weird thing is my phlegm is not overly productive, its actually clear save for the streaks of blood. My chest is completely clear...I dont even have any cough at all.
It does tend to settle down in the afternoon/evening.
I went back to the Doc today expressing concern with the blood streaks and she re-assured me to wait out the course of the antibiotic and it will very likely resolve itself soon...
Also being a triathlete (normally resting pulse 48 and super Blood Pressure, I remember training hard just the day prior to these symptons and 'pushing through'...I regret that now!
Still...its a worry...thoughts?
BAROSINUSITIS (or AEROSINUSITIS)
During deep sea diving, the change in sinus pressure may be very high, causing transudation, bleeding, and edema, especially when pressures exceed 350 to 500 mm H2O. During flying, there is usually less change in pressure than diving. When there is obstruction of the ostia, changes in sinus pressure similar to that of diving may occur.

The Sinus Block
If you have never had a sinus block, it is easy to underestimate how painful it can be. Anyone who has suffered pressure-induced sinus pain will assure you it is extreme and quite incapacitating. The cause of sinus pain is very much like that of ear pain, and it occurs on descent if there is blockage due to inflammation.
People often think if there is a mild amount of pressure at 4000 feet, surely it will not be so bad at ground level. Wrong!
In those few seconds of final approach, the pressure change is so much it can cause excruciating pain. The head feels like it is about to explode. Vision can become blurred or double. Blood vessels inside the sinus sometimes burst, filling the sinus cavity with blood.

Sinuses are air-filled cavities in the bones of the face and skull, and are connected to the nasopharynx by small openings. If these openings are obstructed by nasal congestion, there may be considerable pain on descent. The Valsalva manoeuvre may help, but it is better not to fly with nasal congestion, head colds, hay fever or sinusitis. However, if it is essential to fly, the use of a decongestant spray before take-off and before the start of the descent may prevent the problem.

Barotrauma sustained from flying or scuba diving can cause hemorrhage within the paranasal sinus cavities with subsequent epistaxis.

Recurrent sinus barotrauma is an uncommon condition but it may terminate the career of an aviator. Sinus barotrauma occurs almost exclusively on descent and probably results from occlusion of the sinus ostia through a combination of mucosal disease and anatomical abnormalities. Traditional methods of treating sinus barotrauma have achieved mixed results. In a study by O’Reilly et al, functional endoscopic sinus surgery (FESS) was employed to treat the patients.

As an aviator goes to altitude, the outside pressure decreases, and discomfort may be felt in the obstructed sinus. It is usually not severe, however, and most often air forces its way out past the obstruction. When the aviator descends, the pressure in the obstructed sinus remains less than the surrounding pressure, creating a vacuum effect on the delicate, thin, mucosal lining and resulting in pain that is often severe. Some fluid may be drawn into the cavity, but the more serious complication is pulling away of the mucoperiosteum, with formation of a hematoma. Sinus blocks occur most often in the frontal sinus (70 percent), and the aviator must be grounded until the hematoma resolves, and the ostium is patent. This may require three weeks to three months. For this reason, anyone suspected of a sinus block should have sinus X-rays to determine the extent of injury and then should be followed at approximately three-week intervals, until clear.
